I definitley want your replacement phone to work properly after the most recent update. I see you have tried most steps on your own without a solution. While we recommend performing a full factory reset to remove all apps and install them one by one to get this issue properly fixed, this issue can also be related to your car's bluetooth software. I would suggest contacting your car manufacturer to ensure the bluetooth is up to date and that it is compatible with the newest software. Perhaps they need to send a new update for this feature to work as well. Please keep us posted.
