Did you receive the prompts to access your messages and phone book etc. Try forgetting the device on both the phone and the car. Then re pair them. Just be patient and make sure all the prompts come through. It took me a try or two to get it to work right
What system are you using for Bluetooth in the car? I.e. Ford sync etc
I have a Mitsubishi Outlander XLS with Navigation.
I had a similar issue with my wife's Moto X after the 5.1 update. A simple unpair / repair did not work for me either. Here is what I did. In the phone BT menu select Forget Device. Unpaid from the other end also, or forget (whatever the option is in your car). Then go into Settings > Apps > All Apps. Find Bluetooth Share. Select Clear data. Then reboot your phone. That was the only way the phone would completely "forget" that BT device. Now the BTmenu was completely fresh and no old settings left over. I repaired both of her BT devices and it has been working good again. Maybe give that a try. It seems like a simple unpairing in Lollipop is not really forgetting the old device without clearing the app data and rebooting.
everything was working fine until I did this upgrade to 5.1.
Well that's a bummer. I know how frustrating it can be when things like this don't work correctly. My friend with a Turbo came over last night for pizza so he could download 5.1 with me around (its his first Android phone, he always owned Blackberry for years). I told him about the possible BT issues. After the update we hopped in his VW Jetta and everything worked just as good as it did on KK. Very strange and frustrating at times.Just tried it twice no luck
