Ok so i am having the following problem and would welcome some advice.

My car has bluetooth built in, i can pair my phone with the car and it will work straight after the pairing but if i turn off the car, the iphone will reconnect for about 10seconds and then disconnect. I have tried all firmware versions etc.

My friend had a phone unlocked with ipsf that phone pairs perfectly and there are no problems it works away connects and reconnects etc.

So i decided it must be my phone had a physical problem so i got a new one. Same problem.

Does anyone have any advice ? do you think it could be the unlock methods ?
