I have Sony xperia z3+ and pioneer DEH-X5700BT car stereo with bluetooth, and everything was working perfectly until the latest 5.0.2 update to the phone. All fucntions worked, handsfree, playing music etc from device using bluetooth pairing which always automaticly connected when i stepped into car. Now it always just gives message from my Pioneer headunit: App conn failed, and nothing i have done seemed to have helped. i have tried to reset headunit BT memory and restarting phone and pairing em again and again but without any luck. Do you have any advise please?
