When MediaMonkey for Android plays over Bluetooth to a car stereo that doesn’t support Android Auto, it sends the track metadata (Title, Artist, Album) using a Bluetooth feature called AVRCP. If this information isn’t being displayed on your car stereo, it may be because the stereo is incompatible with the AVRCP implementation on your phone. This problem can occur after a phone update which updates the version of AVRCP used.

For instance, some Pioneer decks that are connected to Samsung Galaxy devices are known to display metadata if the Samsung device is configured with AVRCP versions 1.3, 1.4, and 1.6, but fail to display metadata with AVRCP 1.5.

If you’re experiencing this problem, you can try changing AVRCP settings (usually accessible via Bluetooth developer settings) on your phone.
