Premium Gmapsupp.img – directly for Garmin GPS units

Sorry the downloads on this page are only for OpenMTBMap members - get a Membership here https://openmtbmap.org/support/membership/

To Try Out you can download the map of Austria (and contourlines) for free! All other maps are only for members.

You can also download the Desktop version of most countries for free here: https://openmtbmap.org/download/odbl/:

Why should you download the gmapsupp.img format maps?

As Garmin does not seem to fix MapInstall anytime soon - I've now also made all countries except Europe continent and Asia continent (they are too big) available as gmapsupp.img download - which after unpacking - you can directly move onto your GPS device.

Maps are available Worldwide except for Asia continent map and Europe continent map - as they are too big. They are usually updated every Friday.

Note - this way you loose the possibility to only upload a part of a map to your device as you could do using MapInstall (or Mapsource for Windows users). The advantage is that you can very quickly change the layout (on both Windows, as well as Mac OS x or Linux), and that it's the quickest and easiest way.

If you want to use the maps for planning on your desktop - then you will need the Desktop map too or instead. Note: If you plan a route in Basecamp on your desktop - you should use exactly the same map on your device (so same date, same country - but Unicode/Non Unicode does not matter - so you could use Non Unicode map on your GPS device if needed, and Unicode map on your Desktop/Notebook)

 

- Map Data

All maptiles are compiled with mkgmap using map data from openstreetmap.org & Contributors. You can use and edit the map data by visiting openstreetmap.org.

Contourlines/DEM data:

The altitude data for the contourlines is from varying sources in the following priority (if available):

  1. LIDAR data from open government data and other openly available sources - collected and converted to hgt format by - Sonny - https://data.opendataportal.at/dataset/dtm-austria This data is very very high quality and resolution - there is no better open data available according to my knowledge.
  2. ALOS World 3D30 - überall zwischen N60° und S60°
  3. SRTM 1" v3.0 - very rarely for some tiles missing in ALOS data - also only between N60° and S60°.
  4. Viewfinderpanormas 1" - then 3" - above N60° / below S60° as there is no SRTM data nor ALOS or LIDAR Data avialble.
  5. SRTM v3.0 by NASA 3" v3.0 (very very rarely, 8 tiles only)

more exact info which data is used where - inside the copyright.txt files.

 

Installation:

Unpack with 7-zip (lzma2) .  Recommended tools to unpack:

The default layout is "wide" - the layout optimised for most modern garmin GPS units with comparably high DPI. 

Move the gmapsupp.img file to the /garmin folder on your mSD of your Garmin GPS unit. Note the contourlines (altitude height lines) are always a separate second download - so updates are smaller as the contourlines rarely change. The second reason why contourlines are a separate download is that this way you can change contourlines layout independently from the map layout.

 

If you want to move several countries to your device - you will need to rename the gmapsupp.img file. E.g. just call it mtbmap_Austria.img. Make sure not to use Umlauts or custom symbols ("_"  is okay, better not use " "space. Latin alphabet only)

 

Make sure that the mSD of your Garmin GPS unit is FAT32 formatted. Else it cannot be read by your device. Second - do not forget that most new Garmin GPS devices cannot read Unicode maps - so in that case for maps that have (Unicode) after the name, resort to the non Unicode maps instead.

 

 

If you have not used OpenMTBMaps before - please read through the topic about Autorouting: https://openmtbmap.org/about-2/autorouting/

Map Legend - look at it too so you can understand the map layout better: https://openmtbmap.org/about-2/map-legend/

 

Country-ov.img

This is a basemap of the Country. You can use it if you deleted the original Garmin basemap from your device. In general it's not needed.

 

Compatibility - Unicode vs Non Unicode (cannot authenticate maps)

Newer Garmin devices cannot use free unicode maps (except if you hack the firmware) - usually a "cannot authenticate maps" message which show on boot. The following Garmin outdoor devices are affected:

  • All Garmin devices presented 2016 or newer
  • Edge 1000
  • Epix
  • Etrex 20x / 30x (not "etrex 30")
  • Etrex Touch 25/35
  • GPS Maps 64 series
  • Montana 610, 680 (not 600 / 650)
  • Oregon 700,750
  • Some recent Nuvi devices - as well as some super old devices that do not support Unicode. (E.g. Garmin Vista C, GPS Maps 60 C)

you will need to download the "Non Unicode" version of the map. Only maps of regions where several different scripts are used - are in unicode. I've listed the non unicode maps however also unter the unicode header for convenience (actually only maps with (unicode ) following their name are actually in unicode.

Also english version of maps is only available for countries/regions not using latin only.

 

Adapting The Map Layout 

It's very easy to chose a Map layout:

 

Windows Users - Options:

a) After unpacking just doubleclick the change_layout_mtbmap.cmd it will ask you which layout to chose – and within 2-3 seconds it will be changed.

For the contourlines gmapsupp.img downloads run the change_layout_contourlines.cmd after unpacking. This way you can choose how dominant/thick/thin the contourlines are displayed. By default your device does this automatically – but you can change it to your liking this way.

b) You can also drag or drop any OpenMTBMap gmapsupp.img file directly onto the change_layout_mtbmap.cmd – that’s very useful if for example you want to change the layout of an openmtbmap gmapsupp.img file that is already on the mSD of your device. No need to move it back to your desktop. Just drop it onto the change_layout_mtbmap.cmd and the layout can be changed within seconds. 

Note 1: never drop a contourlines gmapsupp.img file onto the change_layout_mtbmap.cmd – else you will end up with a very strange looking map if the script/program runs at all.

Note 2: Never drop a gmapsupp.img file created with MapInstall or Mapsource onto the change_layout_mtbmap.cmd if it contains several different maps. In that case you will lose the layout for all but one map inside the gmapsupp.img container.

c) Advanced users only – run from cmd.exe terminal:

change_layout_mtbmap.cmd gmapsupp_Austria.img wide.TYP

The first argument is the name/location of the gmapsupp.img file, the second the .TYP-file . It’s easiest to just drag all three files after each other into the terminal. Note – if you want to pass a custom .TYP-file, you have to give the first argument about gmapsupp.img location too. You can also only pass

change_layout_mtbmap.cmd gmapsupp_Austria.img

 
Mac OSx and Linux users:

Note – if you don’t open the terminal in the directory of the .sh file – then first go per “cd”

into the correct folder/directory – then

a) open terminal and run:

bash change_layout_mtbmap.sh

a1) instead of running the script via terminal – make it executable.

either via file properties or in terminal with:

chmod u+x change_layout_mtbmap.sh

Now you can start the script by doubleclick. You can also just drop a gmapsupp.img file in your file explorer/finder onto the script in order to change that gmapsupp.img layout.

The contourlines layout can be changed just the same way using the change_layout_contourlines_gmapsupp.sh script.

 

b) for advanced users – in terminal run:

bash change_layout_mtbmap.sh gmapsupp.img

or 

bash change_layout_mtbmap.sh gmapsupp.img wide.TYP

The first argument has to be the gmapsupp.img file – the optional second argument is the .TYP file (if you want to add a custom .TYP file)

Note 1: never drop a contourlines gmapsupp.img file onto the change_layout_mtbmap.sh – else you will end up with a very strange looking map if the script/program runs at all.

The contourlines layout can be changed just the same way using the change_layout_contourlines_gmapsupp.sh script.

Note 2: Never give a gmapsupp.img file created with MapInstall to change_layout_mtbmap.sh if it contains several different maps. In that case you will lose the layout for all but one map inside the gmapsupp.img container.

 

Map Visibility in Basecamp

By default I've disabled that maps are loaded for display/to show in Basecamp. However if you like to see the map when connecting the GPS device or mSD card to your computer with Basecamp open - you can run the change map layout script (see Adapting the Map Layout above) - at the end of the script you will be asked to enable or disable the Basecamp Map Visibility.

 

Joining gmapsupp.img files for very old devices 

 

Very old devices - Join gmapsupp.img files

Very old devices like etrex vista HCx or GPSMaps 60 CSx – can only use one map file – called gmapsupp.img (max size 4GB). Now if you would like several countries or map plus contourlines to show – you need to join the .img files first.

To do that – add the additional .img files (e.g. contours_austria.img) to the extracted folder of the map. Then run the script:

Combine_all_img_files_into_a_single_gmapsupp_img

 

On Windows you simply doubleclick the Combine_all_img_files_into_a_single_gmapsupp_img.cmd script.

 

on OSx or Linux you open the the .sh script from terminal by

bash Combine_all_img_files_into_a_single_gmapsupp_img.sh

(or chmod u+x to make it executable first, then run it by doubleclick).

Note – if you don’t open the terminal in the directory of the .sh file – then first go per “cd”

into the correct folder/directory.

    Hi, just joined and when I login the download links on this page disappear. Chrome on PC and on Chrome and Firefox on Android. Also the menu system does not seem to work very well on either Android browser.

  • EhrmanFl

    Hi,

    also das mit dem Anpassen der Layouts klappt bei mir nicht. Ich habe einen Mac. Version a1) hat nachdem ich sudo chmod u+x <> eingegeben habe (dann Passwort eingegeben) keinen Effekt. Der Doppelklick danach auf die Datei change_layout_mtbmap.sh führte nur zum Öffnen der Datei und der Text konnte inspiziert werden… (ohne sudo geht’s übrigens gar ned: Access denied)
    Version a)also bash <> führt zu “chmod: ./resources/gmt_osx: No such file or directory
    Missing ./resources/gmt_osx” obwohl die Datei in dem Ordner resources liegt (resources liegt auf der selben Ordnerebene wie die change_layout Datei)…

    Kann mir wer helfen? Achse gleich noch ne Frage: Welches layout ist für wearables (Fenix 6) am geeignetsten?

    Beste Grüße

    • extremecarver

      Wenn sudo chmod u+x beim Skript nicht zum öffnen funktioniert – dann ist irgendwas bei dir mit bash komisch. Du kannst denke ich auch per Sekundärklick auf das Skript in den Eigenschaften die bits zum ausführen (also u+x) setzen.
      Wenn version a) nicht funktioniert – dann gehe erstmal per cd in das richtige Verzeichnis – du bist wohl in einem anderen Verzeichnis.
      Was die fenix6 betrifft – ich nehme an wide. Das Display ist ja recht hoch aufgelöst für Garmin Verhältnisse.

      • EhrmanFl

        Erstmal vielen herzlichen Dank für deine Antwort. Über cd das Verzeichnis wechseln, hat zum Erfolg geführt! Tatsächlich geht das mit sudo chmod u+x nicht. Ist aber auch egal, da Version a) ja nun funktioniert.

        Bzgl der verschiedenen Layout Versionen: Ist ja wirklich cool, dass du das hier überhaupt anbietest. Die Unterschiede erklärt hast du ja bereits, für mich als Laie wäre es noch etwas leichter zu entschieden, wenn du vielleicht einen aussagekräftigen Kartenausschnitt mit den verschiedenen Layouts vergleichst. Ich könnte mir vorstellen, dass einfach verschiedene Screenshots mit den unterschiedlichen Layouts für viele eine Hilfe wären. Vielleicht macht das aber auch keinen Sinn, da es ja bei jedem Gerät unterschiedlich aussieht…

    After updating my 1030 to version 8.0 the map no longer works. I reformatted the sd card, copied the .img file (as I’ve always done) … but nothing. The map no longer appears among those available

    • extremecarver

      which map exactly? Can you post a screenshot of the mSD card content inside the garmin directory? Either you use a unicode map or you made something wrong. Cannot happen due to the update. Or you reformatted the sd card wrongly – that’s most likely! It needs to be FAT32 (and not exfat for example). Use cards up to 32GB and no bigger.

  • makollroser

    Irgenwie bin ich am verzweifeln (oder zu blöd). Ich bekomm die karte nicht auf meinen Garmin Edge 830, beim 820er Edge hat das alles problemlos funktioniert. Was mach ich da falsch?
    Ich hab es mit BaseCamp probiert, und auch direkt ins Verzeichnis vom 830er verschoben. Ich bekomm die Karten aber nicht aufs Gerät.

    Hallo,
    ich habe die Karte von Great Britain runtergeladen und auf meinen Oregon 650 kopiert.
    Die Karte wird zwar im Auswahlmenü angezeigt, aber trotz der aktivierung wird keine Karte angezeigt.
    woran liegt das?

    • extremecarver

      Wenn das jetzt per MapInstall passiert wäre – würde ich sagen es liegt eben genau an MapInstall 4.2.0 – aber du hast ja bereits den gmapsupp.img Download genommen. Kann es sein dass du statt der gmapsupp.img die basemap_great_britain.img kopiert hast? Bist du gerade in Großbritannien? Du musst beachten dass die Karten am GPS Gerät erst deutlich weiter hereingezoomt als in Basecamp angezeigt werden – da voher eine Basemap aktiv sein sollte! Zoom mal auf unter 10km hinein (am einfachsten POI in GB senden, und dann den anzeigen).

    Hello Felix, I’m interested in custom layout, do you know open source software to edit TYP file?
    I only found TypWiz but it’s not free. Which software do you use for your layout?

  • jobricolo

    Pardon, ich habe die Karte Iran in ASIEN gefunden, aber ich verstehe als zeitweiliger Benutzer (sebst wenn ich premium mitglied bin und jedes Jahr automatisch meine donation mache) den Unterschied zwischen Unicode und non unicode nicht. Muss ich auch bei Höhenkonturlinien etwas downloaden?
    Danke vielmals für deine Hilfe

    • extremecarver

      Ja die Höhenlinien sind ein eigener Download. Unicode ist ein universeller Schriftsatz – also Latein und arabisch. Non Unicode lokal (arabisch), englisch Latein (mit automatischer Transkription). Unicode Lokal = lokal egal welcher Schriftsatz, Englisch Unicode = englisch/deutsch wenn vorhanden in OSM, aber keine Transkription.

    Hallo,

    ich wohne im Grenzgebiet Aachen Deutschland, Niederland und Belgien. In der Vergangenheit habe ich mit der Europa Karte gearbeitet und damit Länderübergreifend navigieren können. Wie könnte ich in Zukunft, ohne die Europakarte die Ländergrenzen händeln? Oder waer es möglich die Länderkarten überlappend zu erzeugen?

    Ich habe Openmtbmap Germany hier runter geladen, danach die gmapsupp.img auf mSD-Karte kopiert.
    Im Montana 610 wird das Kartenbild nicht angezeigt. Beim Karten einrichten (Karte wählen) wird aber eine mtb_de_12.08.2019 angezeigt als Aktiviert.
    Die ältere omtb_germany mtb_de-03.11.2018 funktioniert.

    Was habe ich falsch gemacht?

  • Mathias Mezger

    Hi,
    I was really concerned when I ouldn’t install maps anymore. I already thought I have a problem on my good old Dakota20!
    The gmapsupp maps work perfect.
    Many thanks for that!
    Donation is on its way!

      • extremecarver

        Hallo Mathias,
        du hast ja eh schon einen lebenslangen Account – aber seit deiner Zahlung im Mai 2017 kann ich keine weitere Zahlung finden. Wie hast du denn überwiesen? Du mein Banküberweisung oder wolltest du direkt hier per Kreditkarte zahlen?

      • extremecarver

        Ah sorry, CC meinst du wohl Credit Card. Wenn du direkt per Kreditkarte hier zahlen möchtest – musst du aufpassen dass du NACH Eingabe der Kreditkartendaten im Popup – zurück im alten Fenster noch deine Adresse eingibst – und dann mit dem Gelben Pay Now button die Zahlung abschließt – erst dann geht sie durch. (Via Paypal ist teils etwas einfacher – bzw zuverlässiger was Ablehnung durch Bank angeht da meine Website noch keine Mastercard/Visa Securecode bzw ähnliches unterstützt).

    Hi ?

    I downloaded some maps from the site and I copied to the folder “Garmin”( of an external card – formatted MS-DOS FAT32 – of a Garmin eTrek35) the various gmapsupp.img files of the maps renaming them as gmapsupp_italy.img, gmapsupp_france.img, etc; I also copied the various contours_italy.img, contours_france.img, etc files of the contours: but the Garmin eTrek35 does not detect those maps.
    Do I need to configure some parameters (XML files, etc.) and/or run some scripts and/or do some particular actions/corrections (for example, create – on the external card the folder “Garmin\CustomMaps” – and move the *.img files in it) to be able to detect the maps from Garmin eTrek35?

    Thank you!

    • extremecarver

      Is is possible your mSD card is over 32GB? You only need to put the .img into the /garmin directory (not into custom maps!!!). Did you go into the map setup menu of your etrex 35 and enable the maps? Do they show up in the map setup menu?
      I somehow doubt your mSD is really FAT32 formatted (or maybe it’s broken?) or your placed the .img files into the wrong directory.

      • giofram

        Thanks for you aid! ?

        a. the mSD card is 16GB and is formatted as “MS-DOS (FAT32)”: I ran “Mac Os First Aid” and no problems are reported(see image)

        b. the .img files are in “/Garmin” directory (see image)

        c. only Garmin’s maps are available in eTrex35 map setup menu

        Thank you again and I remain available to provide any further information and receive any suggestions.

        • extremecarver

          c) where are the garmin maps saved? Try moving one map to internal memory if it appears on the map setup menu in the etrex 35. Everything looks fine – and the etrex 35 is definitely compatible.

          • giofram

            I moved one map in internal memory and it appears in eTrex35! ???

            1. so, is the problem in the mSD card? eTrex35 and BaseCamp recognize the mSD card:
            1.1 may I “initialize” the mSD card from BaseCamp (or another Garmin software) in a “recognizable mode” for eTrex35?

            2. could I import the .img files from eTrex35 (or Mac directory) to BaseCamp?

            Thanks! ???

            • extremecarver

              Okay – so there is some problem with your mSD card. You could try formatting it on another (e.g. windows) computer – or try another mSD. Clearly your etrex 35 does not recognize it. No neither the etrex nor Basecamp has a format function. Standard FAT32 is the default. Did you send the maps while the mSD was in a card reader or inside the device? If in card reader maybe there is a contact problem? Try if it’s recognized if inside device connected via USB (that will not mean the device actually can access it – the etrex then just works like a card reader)

              2. I don’t know what you mean? You mean read in the maps in Basecamp from mSD instead of installing. Yes it’s possible but very cumbersome/slow – I’ve disabled it by default. You can use the change layout script to enable that option.

              • giofram

                Thanks! ???

                1. as soon as possible (probably already tomorrow) I will format the mSD card in a Windows PC and try to copy the .img files to check if the maps are readable with the eTrex35 (if the maps will not be readable, I will try with other mSD cards)

                2. my need is to use BaseCamp on computers other than my own because – moving in the mountains between shelters and friends’ houses – I can not carry my computer with me and in Italy, unfortunately, the mountain areas are badly covered by the mobile network for internet access (even in the rare areas covered by the mobile network, the connection speed is very low, preventing in fact the ability to download maps);
                being able to use computers made available to me by friends, I can use BaseCamp (of course with the .exe and .dmg installation stored on an mSD card);
                I would then need to store – on the eTrex35 or on an mSD card – the .img files so I can use the maps with BaseCamp so I can view, correct, split, share the tracks (alternatively, I can “upload” the .img files in the app on iOS? and/or there is some app for iOS/Android that can manage the .img files and tracks so as to replace some function of BaseCamp?).

                Thanks again (and also congratulations for the initiative and availability!) ???

                • extremecarver

                  then run the change layout script against all the .img files you use before sending them – at the end of it you can chose to display them in Basecamp – and no I don’t know of a good alternative that works offline. Online there are a few solutions (I cannot tell you which is best).

                  • giofram

                    1. downsizing mSD (from 16GB to 8GB), Garmin eTrex recognizes maps

                    2. the result of the operations on the .img files is as follows:
                    2.1 I ran (macOS: High SIerra) scripts against some .img files (scripts use absolute paths and so I unpacedk the 7z archives in my user root directory) then I copied all .img files to eTrex 35;
                    2.2 but only the .img files on which I did not run the scripts are visible on the eTrex 35;
                    2.3 BaseCamp doesn’t recognize any .img files on the eTrex 35 (do I have to import .img files differently in BaseCamp?).

                  • extremecarver

                    1. there is something wrong with your 16GB card. In general up to 32GB is fine.
                    2.1 what scripts do you mean? The Change layout scripts? They really cannot break the map – but note – you cannot put multiple times the same map with different layout.
                    2.3 – as sais you need to change it with the change_layout_mtbmap.sh script. How to do it is explained on the gmapsupp donwload page at the bottom.

                    2.3 I couldn’t find information around “How to do it is explained on the gmapsupp donwload page at the bottom”: could you list in detail the steps/links/pagine/scripts to follow in order to import the .img files (contours_xxxxx and related gmapsupp_xxxxx) into BaseCamp in a Mac environment?

                    Thanks! ?

                  • extremecarver

                    you cannot import them – you just run the
                    change_layout_mtbmap.sh
                    against the .img files. it is explained at the bottom of the instructions page in detail. Then when you connect the mSD next time – they will be loaded in Basecamp.

                    I tried but I’m afraid I didn’t get the expected results and I can’t figure out what my mistakes are: could you help me to detect them? (I report very detailed information so this could be useful in the future for people who encounter problems similar to those I am facing).

                    I followed these instructions https://openmtbmap.org/it/download/gmapsupp/comment-page-2/#comment-22881 (“Instructions” tab):
                    «Unpack with 7-zip (lzma2) or your preferred unarchiver .
                    Windows: http://www.7-zip.org

                    The default layout is “wide” – the layout optimised for most modern garmin GPS units with comparably high DPI.

                    Move the gmapsupp.img file to the /garmin folder on your mSD of your Garmin GPS unit. Note the contourlines (altitude height lines) are always a separate second download – so updates are smaller as the contourlines rarely change. The second reason why contourlines are a separate download is that this way you can change contourlines layout independently from the map layout.

                    If you want to move several countries to your device – you will need to rename the gmapsupp.img file. E.g. just call it mtbmap_Austria.img. Make sure not to use Umlauts or custom symbols (“_” is okay, better not use ” “space. Latin alphabet only)

                    Make sure that the mSD of your Garmin GPS unit is FAT32 formatted. Else it cannot be read by your device. Second – do not forget that most new Garmin GPS devices cannot read Unicode maps – so in that case for maps that have (Unicode) after the name, resort to the non Unicode maps instead.

                    Adapting The Map Layout

                    It’s very easy to chose a Map layout:

                    a) open terminal and run:

                    bash change_layout_mtbmap.sh

                    The contourlines layout can be changed just the same way using the change_layout_contourlines_gmapsupp.sh script.».

                    I followed these steps:

                    // a. used versions
                    0. macOS: High Sierra 10.13.6; BaseCamp: 4.8.4; MapManage: 3.1.2; MapInstall: 4.3.2;

                    // b. changing contours
                    1. I unarchived contours_italy_gmapsupp.7z in my Mac home directory /Volumes/myDisk/Users/me/;
                    2. I ran /Volumes/myDisk/Users/me/change_layout_contourlines_gmapsupp.sh script (“bash /Volumes/myDisk/Users/me/change_layout_contourlines_gmapsupp.sh /Volumes/myDisk/Users/me/contours_italy.img”) using “4” choice (“4: Default – Your GPS device decides how to display the contourlines.”);
                    3. /Volumes/myDisk/Users/me/change_layout_contourlines_gmapsupp.sh script noticed me “Success – Replaced .TYP file in:
                    /Volumes/myDisk/Users/me/contours_italy.img”;
                    4. I copied /Volumes/myDisk/Users/me/contours_italy.img to eTrex35 internal card /Garmin directory;

                    // c. changing map
                    5. I unarchived mtbitaly_gmapsupp.7z in my Mac home directory /Volumes/myDisk/Users/me/;
                    6. I ran /Volumes/myDisk/Users/me/change_layout_mtbmap.sh script (“bash /Volumes/myDisk/Users/me/change_layout_mtbmap.sh”) using “1” first choice (“1: Wide – standard design for most GPS units with high contrast and wide lines (for medium to high DPI GPS Units)”) and “1” second choice (“Press 1 to make map readable by Basecamp”);
                    7. /Volumes/myDisk/Users/me/change_layout_mtbmap.sh script noticed me “gmapsupp.img will be visible in Basecamp”;
                    8. I renamed /Volumes/myDisk/Users/me/gmapsupp.img in gmapsupp_italy.img;
                    9. I copied /Volumes/myDisk/Users/me/gmapsupp_italy.img to eTrex35 internal card /Garmin directory (to be sure, I copied /Volumes/myDisk/Users/me/basemap_italy.img to eTrex35 internal card too);

                    // d. verifying map: eTrex 35
                    10. map was detected (I saw mtb_it_27.03.2019, italy_11.07.2019_omtb and mtb_it_11.07.2019 in System|Map|Configure_Maps menu as active maps);

                    // e. verifying map: BaseCamp
                    11. map wasn’t detected;

                    // f. checking
                    12. to exclude mSD card problems, I re-installed Garmin default map (a) in mSD card: BaseCamp detected map;
                    13. I moved contours_italy.img and gmapsupp_italy.img to mSD card: BaseCamp didn’t detect map.

                    That’s very strange – you did everything correctly. The problem is – to verify if the flag is written correctly – you would need to use windows, as gmaptool has no graphical version for OSx. I tested that the script runs well under Linux – but maybe there is a problem in OSx – as the gmaptool version for OSx is marked experimental.

                    Oh and yes – the contourlines download script does not have the option to display in Basecamp.
                    Basically the script calls:

                    $gmt -wc 1.00,0 $imgfile
                    where $gmt stands for /resources/gmt_osx
                    and $imgfile is the gmapsupp.img

                    you could open the script in an editor and change line 346 from
                    $gmt -wc 1.00,0 $imgfile >/dev/null
                    to $gmt -wc 1.00,0 $imgfile

                    to see the output. if no output is shown add a line before with
                    set -x

                    As basecamp cannot show two maps at the same time – you would need to first join the contourlines into the map gmapsupp.img using Combine_all_img_files_into_a_single_gmapsupp_img.sh script – then run the change layout for the map. But the problem that it is not showing up is not solved by that.

                  • extremecarver

                    oh sorry – forgot if you run the combine script – you can already set the basecamp visibility….

    Hi 🙂

    If Europe map is too big, Can you make a mtb map for Pyrinees as for Alps?

    • extremecarver

      Hi Davide,
      I can only create maps for the same areas as covered by the geofabrik OSM extracts – there is none for the pyrenees.
      You can use MapInstall (on windows also Mapsource) – to send extracts from the Europe map to your device.

    Hello, can you please explain how to load the map on a new garmin edge explore? I tried to put into the device (garmin folder) both the unicode or non unicode gmapsupp.img file but this is apparently not recognised
