Who knows how to pair Garmin Mobile XT with non-Garmin GPS (BT338)?
Nobody does…. Garmin’s new (and currently Beta version of the) Mobile XT application will ONLY work with Garmin’s GPS 10 Bluetooth receiver at this time. GPSProxy does NOT work with Mobile XT because Garmin changed the way that Mobile XT interacts with the Bluetooth GPS receiver (i.e. I wouldn’t hold my breath that Mobile XT will work with GPSProxy any time soon).
