This is on my Razr Maxx HD with Jelly Bean. When I use the stock Google Play Music app and play music via Bluetooth through my car's JVC X50BT receiver, the receiver sees the track information and can tell me song title, artist, time, etc. The JVC unit supports A2DP 1.2 and AVRCP 1.3 and the Maxx HD supports A2DP 1.2 and AVRCP 1.4 (from what I could dig up).
But if I use a third party music app (Music Folder Free or Smart AudioBook) via Bluetooth, my car's receiver only says "Pause" as if it's not getting anything from the phone. However, the music does in fact play through the speakers, and I can even go forwards/backwards to skip tracks using the receiver's buttons.
Is there something special about the Google Play Music app that allows only it to do this? The reason I ask--and it's pretty trivial in the grand scheme of things--is that when the JVC unit displays "Pause" all the time when I'm using a third party app is I can't see what time it is on the clock. I can hit "Disp" on the JVC unit and it'll give me the current time for a few seconds, but then it reverts to "Pause" and stays there. But if the unit's receiving info like it does from Google Play Music and is in "Play" mode, then it'll display the clock all of the time. Kind of weird functionality, but it's why I ask.
