Bluetooth GPS compatibility list for Android 2.2 / Archos 43 tablet? I've been looking at a very inexpensive bluetooth GPS (DeLorme Earthmate BT-20) to pair with my Archos 43 Internet Tablet running Android 2.2.  Is anyone aware of a compatibility list that I should be referencing when considering pairing my device with a bluetooth GPS?  I assume that the Android app will be used to reference maps, and the GPS will simply provide coordinates, but I may be mistaken.
I don't believe you need to worry about hardware compatibility beyond the BT specs.  Your A43IT uses Bluetooth 2.1 EDR so as long as the BT GPS supports that it should be all set.  You'll either need an internet connection to use Google maps, or like you were planning, an app that downloads the maps, like CoPilot. 

I haven't gotten around to buying one yet, but I've been doing some digging in preperation.  Here's some links that may help:

Here's another relevant thread... and another.


Let me know what you end up doing and what works in case you beat me to the setup.
