iPhone 4s os 6.1.2 + Volkswagen Universal Bluetooth.
The problem that I'm experiencing is that, apparently, I'm correctly connected to my car hands free system (network, signal level, battery level correctly shown in my dashboard) but sometimes, when I receive a call I can't answer from the hands free. From that point on (after missing the call) if I try to make an outbound call I get a Bluetooth connection error and get disconnected. The only way to connect again is switching off Bluetooth and on again.
As said, this happens sometimes but not always, so troubleshooting this one is almost impossible. It seems to me that the connection error is always produced by an incoming call since I have never found the error when dialling an outbound call (except in the case said above).
I have re-paired both devices after every software update and none has solved this.
Very difficult to me to say since when I’m experiencing this. Until last November I had an iPhone 4 which worked flawlessly with the same Volkswagen unit, although it ran just a few days with os 6.0 so, maybe not enough to find the problem. I started to notice it with the 4s which came with os 6.0
I have read a few posts before that the iPhone 4s is the first to be compatible with Bluetooth 4.0 and that they have discontinued the compatibility with previous Bluetooth versions. Is that true? … if so we may never get a solution to this because I don’t think that Volkswagen (nor most car makers) will invite us to upgrade our Bluetooth hands free systems.
Thanks.
