My phone has been working great in my G37 coupe, but tonighht it started doing something weird. When I place a call, the nav screen shows the call being started, then the screen changes over to the nav screen and drops the call. Any ideas on what might be wrong?

 

I just started noticing that on mine as well. Although the car's display looks like the call was dropped, the handset actually completed the call, but u can only talk using your phone, not through the car. I have an iPhone 3GS, btw. Haven't found a fix yet.

 

Is this a consistent problem (happens with every call?), or just an occasional one? Have you:

Turned your phone off / on again?
Re-paired your phone's bluetooth connection with your car?
Tried pairing another phone with your car to see if this still happens?

If the answer is 'yes' to all of the above, I'm not sure what to tell you apart from perhaps take it into a dealer and have them take a look. Hope that helps.
