I'm sorry to hear you are having issues with your bluetooth connection. What model is your car?
The following two articles may be helpful for this issue:
Some car stereos and accessories that use Bluetooth for control and playback may require a firmware update to work as expected with the AVRCP 1.4 support added in iOS 6.
Symptoms may include:
- Unable to control playback through Bluetooth
- Song name, artist, and other information is not displayed on the car stereo
iOS 6 supports AVRCP 1.4, the latest Bluetooth standard for control and playback. Your car stereo (sometimes called a head unit) may require a firmware update to correctly support the Bluetooth standard.
Several manufacturers, including Advent and Pioneer, have announced plans to provide an update or already have one available. Please contact your car stereo manufacturer to see if a firmware update is available.
I hope this information helps ....
Have a great day!
My wife also had this problem after updating to 6.1.4. We called Apple Care support and they instructed us to contact the manufacturer of our car stereo for a firmware update. Crazy! We were able to pretty easily solve the problem.
Before doing anything drastic like wasting several hours searching for a firmware upgrade for your car stereo, I'd suggest simply removing the bluetooth profile for the car stereo on your iPhone, and removing the phone profile from your stereo.
On iPhone this is done under Settings > Bluetooth. Select the blue arrow next to the car profile name, in our case "My Car". Click "Forget this device". You should be able to find instructions for this in your stereo manual to do this on your stereo as well.
After the device profiles are deleted from both the phone and stereo, simply pair the devices again. This worked for us first try.
