I'm using my Nexus One with Android 2.2 Froyo in my car dock. For the audio output I'm using a a2dp receiver which is hooked up to my car stereo. Now, when I put the phone in the car dock it automatically connects to the car dock but not to my a2dp receiver, I have connect it manually in the settings (already paired).
I'm also using a custom app for audio playback. I thougt I maybe could force the a2dp connection to the a2dp receiver. But as far as I know, the default Bluetooth API does not support such a thing.
Is there any Intent for establishing the connection, or any other way? I would also accept an undocumented solution.
