Thread: Garmin NUVI 3760T and 3790T

I make-it work. Thanks for the tip aekhong.
I must rename the mapset of img, because all maps have the same name.
On my SD card I make 2 folders garmin and map. In the map folder I put the maps.img renamed also renamed the mapset, on the garmin forder I have POI folder where I put the proximity poi's like speed cameras and others.
