Hi,
I connected a Adapt AD-700 Sirf III GPS device to my Archos PMA 430 with a Sweex bluetooth USB dongle. Class II because of battery live.

Works fantastic.

I have tried a Globalsat BR 303, USB GPS mouse. No GPS fix in 15 minutes. The Adapt has a full fix in seconds, even indoor or in the car. Spent the extra cash for a good GPS receiver.
