When I connect my Alpine CDE-HD137BT car stereo to my HTC Thunderbolt running Pandora, the connection is made and the music plays. I can even skip, pause and play songs from the car stereo buttons. But the Pandora app on the phone just shows a black screen with:
^v (up/down arrows)
...and not the regular Pandora screen with the artist, track name and cover art.
If I go to the Android notifications screen where it shows what song is playing in Pandora and touch that notification, it takes me to the Pandora app and very briefly (for a fraction of a second) shows the regular Pandora screen, then immediately goes to the screen described above.
The Menu button when the screen describe above is showing only gives one option: Quit. This, of course, ends the Pandora app altogether.
I've seen videos online of others controlling Pandora on their Android phones from this particular stereo unit, and the normal Pandora screen is shown on the phone, which should be the norm here.
Any guess what's causing this? Anyone seen it before?
I'm running a rooted version of the stock Gingerbread image.
