Hi Nick, You may remember I had some difficulty in bringing up the Bluetooth UI on Android. I have passed that stage now! I am able to connect to headset/handsfree devices.
But, I am still looking for a procedure to check A2DP from the UI. Can you list down that procedure? By the way, do I really need a song file in a sdcard to do all this. Because, I get this message that "No song in sdcard"!! I think I am almost there..and dying to listen to a nice song on my stereo headset!
