From the perspective of my Galaxy S3 it connects to my 930BT successfully in both phone and audio mode. However from the Bluetooth screen of the player the phone appears to be perpetually connecting. No songs appear in the directory and although play can be pushed nothing plays. I have played with the Bluetooth settings and re-paired numerous times to no avail. No A2DP success.
However today I discovered another way that works. Rather than connect via the Bluetooth settings start with the Android Player app. Use the menu ( lower left) button to share via other device. Select Bluetooth, connect to 930BT and voila, streaming audio. Note that this will not work if your phone is already connected. You must start paired but not connected.
Unfortunately this only starts an audio connection. To add a phone connection return to Bluetooth settings an check the phone box. Phone connectivity will then be added and things will work as I had hoped they would from the normal settings screen.
Based on the above I'd conclude the AVIC is functioning as it should but the Galaxy S3 lacks the logic to trigger the player to conclude the A2DP exchange.
I'll post this to a few Android forums and see if we can get that fixed.
Reply if this fixes your problem. I'd like some idea of how many people have this issue.
