How soon after getting into the vehicle and turning the key on are you trying to get the Aux to play? It may just be the time period that the phone and Uconnect are bonding, the phonebook downloading and other profile handshakes. A2DP (for streaming audio is the last profile to shake hands). This may be why you're getting that message. Usually that will appear if the phone isn't paired up and bonded yet.
Do me a favor, turn the key on or start the motor and wait for a few minutes to see if the Aux button goes blue.

When I restart the car I can click on the aux button like normal but then get the 'this device is no longer available'. Have no clue what's going on especially since my uconnect works. Has this happened to anyone?
