There is an experimental driver for Garmin IMG maps.

It's located here: http://libgarmin.sourceforge.net/ You will need the 'subversion' (svn) tool to install this driver.

You can search a map for your area at: http://gpsmapsearch.com/ http://mapcenter2.cgpsmapper.com/

You can build your own from OSM data see: http://wiki.openstreetmap.org/index.php/Mkgmap

Driver supports only maps that are not locked! Some of original Garmin maps are such, MetroGuide europe for example is NOT locked. But most of them are locked!

Note that many features are not yet implemented (such as navigation).

Please give us feedback / bug reports/feature requests/success stories about this driver either in navit tracker or mailto:libgarmin@gmail.com.

Prerequisites

First, get libgarmin from svn, and install it, as usual :

svn co http://libgarmin.svn.sourceforge.net/svnroot/libgarmin/libgarmin/dev libgarmin
cd libgarmin
./autosh.sh
./configure
make

And, as root :

make install

How to build the driver

Be sure to update navit to latest cvs

reconfigure and build navit.

cd ../..
./autogen.sh && ./configure && make

Configure your map source

Now add your first garmin map to navit.xml

       <mapset enabled="yes">
               <map type="garmin" enabled="yes" data="/path/to/gmapsupp.img"/>
       </mapset>

Where you can give it either dskimg file (gmapsupp.img) or a .tdb file

Note that only one mapset may be enabled, so if your existing navit.xml has another mapset enabled (default), you need to disable it by setting

       <mapset enabled="no">

You also need to add

       <plugin path="$NAVIT_PREFIX/lib/libmap_garmin.so" ondemand="no"/>

to the plugins section on the top of navit.xml

Install a free basemap from Garmin

You can download a free base map from garmin. http://www8.garmin.com/support/download_details.jsp?id=3645

After you get GarminMobileXTFreeBasemap_4xxxx.exe, unzip it to some temporary directory. In GMobileCard/Garmin directory you will find a file called gmapbmap.img. Copy that file in some location for later use, let's say /mymaps/gmapbmap.img . Now you can remove the temporary directory. And register the map in your navit.xml

    <mapset enabled="yes">
           <map type="garmin" enabled="yes" data="/mymaps/gmapbmap.img"/>
     </mapset>
