Some car stereos require a firmware update for AVRCP 1.4 Bluetooth compatibility

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.

This article has been archived and is no longer updated by Apple.

Symptoms may include:

  • You can't control playback through Bluetooth.
  • Song name, artist, and other information doesn't appear on the car stereo.

iOS 6 or later 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.
