Garmin Deutschland/Germany Topo V3 - Mapsource
A small hint for people having a problem with Mapsource and this version of Topo DE V3:
if the program crashes when you select an area giving you a error message containing the TPDEUEC3_trf.trf file and you don't have this file in the Garmin map directory (the above version at least doesn't create one), then go to the registry HKEY_LOCAL_MACHINE\SOFTWARE\Garmin\Mapsource\FamiliesNT\FAMILY_446 and delete (or rename) the registry concerning the TRF file.
After doing this, everything worked fine. The install.bat seems to make an TRF entry in the registry that crashes Mapsource if the file is not there, but you don't need it.
