Just had a 940 put in to replace an AppRadio.
I see in the settings an option to change "app mode" to Bluetooth instead of the default "wired". When I do this, and make sure my iPhone is connected, the buttons for Aha and Pandora are no longer greyed out. Though when I try to launch them, it says "Bluetooth is disconnected". Everything plays fine over the Bluetooth audio option.
What am I missing?
