Good to hear that on Huntinggpsmaps. I've been looking at his plat maps. I know for a fact the SD cards you buy directly from Garmin, you cannot look at on you PC. I contacted them, and that's what they said. Funny thing, when someone stole my GPS from my truck, Garmin said they couldn't track it. So no home study of the maps if you buy their SD card.. Thats when I started to get in maps from gpsfiledepot.com and they are great and the price is right on most...free.
