So you're using the cellular version correct? I debated tablet vs GPS unit but after reading the mess with Garmin stuff. I'm definitely NOT going that route. Too bad, they were an early pioneer in handheld GPS, just turned into a big co. with ************ service now it seems. As for tablets, iPads are nicer and would run better I'm sure, but you cannot run an external antennae with one if I'm not mistaken, so I would have to go the cellular route, then add a line with ATT~
Without cellular, it's all dead in the water correct, or would GAIA run using the GPS built-in with the tablet with whatever basemaps it had at that time? I just got my HAM license as well, and have GPS on my Kenwood TM-710, and can output coordinates to aprs.fi and see where I am on the map, but pretty sure I'd need the cell service to run that app in the browser though correct? Worse case, I get live coordinates in Lat-Long on my HAM, then compare and get a good idea where you are, but just trying to see what I need for my setup.
