A:AnswerRead my 32GB card just fine. If your looking to use it for waypoints from MapMaker, forget it. Doesn't read GPX files. So anything about a 8GB card is a waste.
A:AnswerThis device can load POIs for geocaching, however it will not load any type of topographical mapping so it would be more difficult to use it for geocaching. It is recommended to use an outdoor unit by Garmin.

A:AnswerTake it back for Geek Squad protection and get a new one. I've had them do that in the past. Never had a problem getting an exchange either. I ALWAYS buy the protection on my Garmin's!
A:AnswerI'm not an official authority on this, but I just bought the 52LM and my mom just bought the 50LM and we see no real difference between the two. From as near as I can tell, the 52 is just a new model number for what is essentially the same device.
