After you turn off the car, wait about 2 minutes until the PRND lights turn off-- then the car is "shut down". If that doesn't clear the issue, you could try a hard reset (search the forum) or, probably wiser, talk to your dealer.
I received this exact error tonight after re-starting the car from a brief stop (10 minutes). I will check to see if the error resolves tomorrow morning. I took a picture of the error message in case anyone is curious what the screen looks like.The entertainment system seems to have weird quirks all the time. The other day when receiving a call the sound went out after I hung up and never came back. Yesterday, the system kept saying "Connecting to Audio Source..." forever.
The only thing that seems to clear it is letting the system completely shutdown. Does anyone know how to do this? How do you shutoff the entire system? If you lock the doors and walk away it stays on in some sort of sleep mode. It seems only that you must be away from the car for some period of time.
I have seen this too, not sure if it has occurred since the 510 update, but when it does occur, it goes away with a soft reboot (shut off car, wait 2 minutes, reboot).I received this exact error tonight after re-starting the car from a brief stop (10 minutes).
