Hello all. I'm planning on grabbing one of the iPhone GPS apps while they're on sale this weekend. I am having problems getting information on any of the major players (TomTom, Navigon) as far as supporting audio routing via bluetooth headset. My primary use for this would be on a motorcycle, using my BlueAnt Interphone headset which is mouted on my helmet. It is mono (non-A2DP), and I've already discovered that it will not play the music from the iPhone. This was a pretty big bummer, but calls still come through very well so it is working for now. Does anyone know if any of the GPS apps out there will route audio prompts to a mono bluetooth headset?
