Answering a bluetooth phone call with car kit
Does anyone know how I can answer the phone in my A3? Its a GSM kit with bluetooth and the phone connects up great and the dis displays incoming call details, but when I receive a call the phone rings (through the symphony) and if I answer on the phone (press the green pickup) then the phone answers by itself and not through the car.
If I go into my phone settings (during the call) and say switch to hands free, it connects great and I`m then using the kit properly.
Outgoing calls are fine.
Is this a phone bluetooth software version issue or do I have to have a cradle to use the PTT button to answer the call via the car?
Any help would be appreciated. Also how much is the cheapest cradle you can get if the PTT button is the answer?
