Hello together, have been having problems with the phone call over the hands-free device for a long time. The phone connects via Bluetooth without any problems at the start of the engine, but then loses the connection quite quickly (approx. 2- 3 minutes). Can then connect again, display in the car shows then also again the phone and shortly afterwards the coupling is lifted again. Can then repeat as often as possible. In the spring afterwards a software update was made, but did not bring any improvement. Since approx. 1 week the radio spins to it. Sound is short away, then continues to play, again short sound oscillations, and so on and so on. Display then goes completely out of time and again. Errors do not always occur. For ideas I would be very grateful Fzg is a V 70 III, year 2007 with Premium Sound
