For some time now, I have had the problem that the Bluetooth connection in the car is established immediately, but voice transmission and access to the phone book, for example, is only possible after about 10 minutes of driving. Can anyone help me? Furthermore, on hot days, the microphone fails again and again after about three minutes of conversation, and I can only make phone calls via the loudspeaker...
