So I got Garmin Mobile XT. And I road around using it today. Definetly gives better routes than Sprint Navigation and has some features Sprint Navigation does not have. Although I wish it spoke street names like Sprint Navigation. Overall though I think Garmin might be a little better, but it's still early in my use of it.

Anyway, it didn't help beat the heat. I ran it with the device closed in portrait mode and the internal temp went up to 47 degrees C when I used Garmin while playing some music, all off the SD card. Maybe keeping it landscape with the keyboard open might have been enough to keep things cool, but it was not with Sprint Navigation. I guess I'll need more testing. I've got a long drive coming up and I'm going to just use the cold pack because I know that works. I can do more testing without the cold pack later.

With Garmin Mobile XT, I do have it pulling data such as traffic information. But the maps are on the SD card, so I doubt very much data is being transfered.

Question for anyone using Garmin or IGuidance, if you've found either does not cause your device to overheat, are you pulling in any data such as traffic information, or running the program without pulling any wireless data at all?
