Hi all. I also have been using garmin.osm maps that are already made...and can easily put the .img file into the Map (or Garmin) folder. I can even see the map I've uploaded to the device in the list under Settings/MyMaps... But...for some reason, I cannot get the device to SHOW the map...it seems to revert back to an older garmin map on the device (I check using a specific feature that I know is in the OSM and not on the Garmin map. I try de-selecting the Garmin map, leaving only the OSM but the device keeps "re-selecting" the map. I am using a Nuvi 3790, and it has two versions of garmin maps on it...and the osm routable map that I just transferred to it. In basecamp, the osm maps shows on the device as well. Not sure why I can't see it on the device. Can someone explain (in non-technical language) what is happening? This is so frustrating. Thanks. Cindy
