Hi there, I'm a cross border employee and would like to use navigation my Galaxy i7500 whilst roaming and minimize cost at the same time. I have AndNav2 set up with maps of western Europe cached on the SD-card. Since A-GPS still generates data traffic (and having disabled this option whilst roaming), no position data is available. I still have an external bluetooth GPS receiver and paired it with my Galaxy. How do I get my Galaxy to use the external GPS source for apps like AndNav2 or Google Maps for that matter. Any help is highly appreciated. Bets regards, Qwasi.
