Android Bluetooth Profile - AVRCP Version on JellyBean My Car audio system supports AVRCP v1.3 which, when my iPhone 4 buddies play music over BT, the song title is displayed on the radio... I have just upgraded to JellyBean and find that i am still not having any luck with my android device 

Phone Specs


Samsung Galaxy s i9000 
Android Version 4.1.1
ROM MIUI-2.10.5 JellyHeff


Wikipedia quotes:
AVRCP has several versions with significantly increasing functionality:


1.0—Basic remote control commands (play/pause/stop, etc.)
1.3—all of 1.0 plus metadata and media-player state support The status of the music source (playing, stopped, etc.) Metadata
information on the track itself (artist, track name, etc.).
1.4—all of 1.0, 1.3, plus media browsing capabilities for multiple media player Browsing and manipulation of multiple players Browsing
of media metadata per media player, including a "Now Playing" list
Basic search capabilities


Any Ideas where the problem is?
I don't think that base android supports avrcp beyond version 1.0.  A lot of the community created ROMs have added support for the other levels into their custom systems. However the stock version doesn't have it.
