About the Maps - Please Read

Maps are available Worldwide. They are usually updated every Friday.

- Map Data

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

Thanks to Geofabrik for providing the map data snapshots which I use to create the maps.

Thanks to for the best DEM (contourlines) available on the net.

Super short Instructions:

Installation is in principle easy. Unpack with Unarchiver - then install with doubleclick. However here are the detailed Instuctions for Installation and Newbies. It also explains how to change the map layout - which is a must before sending them to your GPS:

For The Europe continent map, and all maps that have the contourlines as a separate download - please make sure to read the above linked tutorial (you additionally need to extract one folder and move it to the right location).

Programs to Display the Mac OSX Openmtbmap

Please use the latest Garmin Mac OSX Basecamp Version. Maps are not compatible with Basecamp v2 or older (as well with other old Garmin Mac OSx programs (e.g. Roadtrip)).

Problems - Help - Tutorials

Beginners Guide can be found here: get started with openmtbmaps

An installation guide and general MAC OSX specific Tutorial can be found here

Send Maps to GPS with Basecamp/Mapinstall: tutorials/send-maps-to-your-gps/mapsource/ I recommend to always send maps to an external data card and not internal memory. (this way if something goes wrong, or maps would be damaged you run less danger of wrecking your GPS).

Current Issues

The address search is not working consistently. Most problems are due to inconsistent data structures in OSM address data.

- General: Autorouting over longer distances on GPS works only with Via Points. plan-routes-efficiently

- Autorouting needs attributes like tracktype, bicycle routes, mtb:scale, sac_scale, mtb routes and others to work well. So keep care to enter those details into OSM. (not all are needed, but enough for me to guesstimate wheter a street is cyclefriendly/mtbriendly or not).

- Non Connected ways and overlapping ways without node, this is the main problem and a problem of the underlaying map data - please check here: Only check/enable: "almost Junctions" , "intersections without junctions" as well as "overlapping ways". This helps you to quickly spot the erros. You can then follow the link to Potlatch (or also JOSM is integrated for JOSM users) and quickly correct mistakes! Watch out not to connect ways that are not connected in reality (i.e. a way crosses another on a brigde, here no connecting node is the right solution). - If you use Windows 2000 you may need to install the "reg" command : Reg cmd at Microsoft. Batches are incompatible to earlier Windows versions. - Note sometimes sea is missing. This is not an issue, but currently not differently possible. It is usually a problem in OSM data.

Notice on Updating Maps

If you want to be notified by email on map updates please go to the frontpage and enter your email address in the subscribe field of the left sidebar. You only get an e-mail when there are changes besides a simple map data update. Map updates are usually every Thursday night / Friday morning. You can look at the server to see the date of map upload. To update the maps, simply overwrite the old data or use Mapinstall.

Overlapping maps in border regions

While you can join maps of different countries, routing over the boundary is a bit shaky, and you will have one map overlaying the other with white background. As long as mkgmap cannot create randomly shaped overview maps (currently only rectangles), this problem is not solvable. There is however the possibility to download a Europe map, which will be updated every 4-6 weeks.

Velomap and Openmtbmap of the same Country -- Problems

If you install an openmtbmap and a VeloMap of the same country with contourlines as separate download (and Spain as well as Canary Islands), you should only send the contourlines once (meaning with either Openmtmbap or Velomap of the country). Else you GPS might not show the maps, or worse not even start until maps are deleted.

Therefore: Install one map without conoturlines. E.g. install openmtbmap Europe with contourlines, but do not install the contourlines for Velomap Europe.

-- This is not a problem with countries where contourlines are fully integrated like Germany, Alps, Austria,......

Compatibility - Standard (Unicode) vs Non Unicode (cannot authenticate maps)

In general just download the Maps from the first "OpenMTBMap" tab - they are in unicode if useful. If you get the message - "cannot authenticate maps", and you have  you have one of the following devices:

  • All Garmin devices presented 2016 or newer
  • Edge 1000,820,520
  • 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 instead. So get the map from the "non unicode openmtbmap" tab instead. Only maps of regions where several different scripts are used - are in unicode. If Latin is the predominant script - then of course no unicode map is offered. If your device can display Unicode maps - then of course get the standard version - meaning Unicode.


Please comment if you like theese maps or even better tell other people about them (forums, blog about it, twitter, etc…) In case maps break Basecamp or don't work - please write exactly which downloads don't work and the time of download as well as your OS and Mapsource version.. Before posting problems please read through here and here though FAQ

And don't forget if you have problems unpacking the maps - .7z is a container, the actual compression I use is the very modern lzma2, most .7z archives however use the older lzma compression, therefore make your you use the latest Unarchiver or another program that can unpack lzma2!

Openmtbmap maps Premium Download in Mac OSx format (gmap)

Upon several requests, I have decided to make available all openmtbmaps and velomaps available for download in Mac OSx gmap format for Basecamp. This saves you the hassle of converting them. All countries will however only be available for download for openmtbmap members. Austria is available as a download to everyone, so you can try it out.

So to try it out download the Map of Austria: Austria

If you want to know the last update time, MD5 Checksum or exact filesize of a download - just look into the MD5 link that follows each download.

Contourlines Downloads

Most countries, especially the popular ones, have the contourlines already integrated. However for several countries the contourlines are rather large (rule of thumb if contourlines have more data than the maps) and I integrate them, but you need to download them separately (once).

In general it is fine to only update the map, as I try to change the contourlines as seldom as possible. Installation instructions for contourlines Point 2a here: Install contourlines on Mac OSx

Non Unicode Maps - Only offered for Non Latin Using Countries/Regions

You will need to download the Non Unicode Version if you have one of the following devices:

  • All Garmin devices presented 2016 or newer
  • Edge 1000,820,520
  • 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)

This is due to a firmware bug that Garmin introduced as part of their efforts to cut down on people "pirating" their maps. However by doing that they also cut down on Unicode maps produced by mkgmap or even some of their old (legitimate) maps which are not running anymore on these devices. You will know that you need to use the Non Unicode map if on boot your GPS device tells you to "unlock maps". Why is the Europe Map in Unicode? Well for example in Greece and some Eastern Europe countries the script is Cyrillic not latin - and only Unicode maps can contain both scripts in one map. So the non unicode map will not correctly show labels in such countries. Use the country non unicode map instead. They are always in the predominant script of the country.

Note1: if you install the non Unicode version of a map - you will overwrite the Unicode map. You can only have either or installed.

Here only those countries are listed - where the standard download is Unicode. If you don't find a country here - look at the standard downloads.

Contourlines are identical to Unicode maps.

Note - if a country is not listed here - it means the normal map is non unicode anyhow. Only maps with (Unicode) behind the name are unicode. E.g. for Germany there is no need for a Unicode map - as only latin is used in Germany.

Note - local language maps of: Sri-Lanka, Nepal and Cambodia are in latin1  - so the local language maps are not very useful. There is no ANSI Codepage available (besides Unicode) that would support the script/garmin units. Israel-Palestine map is in hebrew (so the Palestine area is not useful). Afghanistan codepage is for Dari - Pashto is not supported outside of Unicode.
