My CD player suddenly stopped working this morning....getting external system not connected error. Don't want to pay a dealer to reconnect a loose wire if I don't have to. Has anybody ever had this happen?
Does the radio play? AC work (can you control it)? If not, either you have a loose or shorted connection somewhere on the AVC network, or the MFD has gone bad. There was a known problem with the MFDs on earlier 2004's.
