When you updated, did you also update the bluetooth to 3.24? I forgot to do that and could never get pandora to sync with my phone. I updated the bluetooth and all is well now.
Sorry I missed that you had to change the App connection type from Wired to Bluetooth in settings, but still - neither app connection will stay connected or ever show the display on the head unit. You have to mess around with the settings just to get the apps' audio to finally go through the car, and when it finally does, the disconnected bluetooth message continually stays on the screen no matter what and eventually the audio drops back to just through the phone too. Completely broken here and useless. This goes for Pandora and Aha.
OP do you know why this isnt working properly at all?? I see above that two others have the same issue and I'm sure everyone else with Android as well....
