Okay, so perhaps I am jumping the gun here but now with 4.2 and apparent GPS support, I am keen to try a GPS receiver and see how it works with the BB maps application. The Navibe GB735 Bluetooth GPS Receiver found at
Navibe GB735 Bluetooth GPS Receiver(SiRF III, WAAS)(Free Arkon Vent Mount) looks interesting and a good price.
Anyone either tried one of these devices with a Blackberry unit. Any comments, issues, advice?
