I have been doing some searching and can find plenty of bluetooth transmitters to plug into the headphone jack of any mp3 player, but I want to go the other way..
I want to use my droid as a mp3/media player when in my car and eliminate the need to have the aux cable plugged into the droid... I want to plug the aux cable into the bluetooth receiver instead. Ideally, the bluetooth receiver would be built into a 12v adapter charger so i could just leave it charging all the time.
I read some conflicting posts about A2DP, but since this is for music, that would be best as well.
Can anyone point me in the right direction?
