So, I've been struggling to get the track images to appear on my Garmin Drivesmart 60 and 61devices to no avail. I'm starting to think the Drivesmart series don't support the gmapsupp.img file format. I hope I'm mistaken. I decided to load this same gmapsupp.img file into the "Garmin" folder on a Nuvi 265W that I have, and I can see my track overlay just fine on this device. Am I missing something in regards to loading onto my Drivesmart devices or is it just not possible? I'm loading the .img file directly to the device in the "Garmin" folder as I don't have an available memory card. Works just fine on the Nuvi 265W. Really been scratching my head with this.
