I own a 2006 SL500 and I get a message on the dash instrument cluster that says, "convenience function temporarily unavailable." This happens when I start the car. When it appears I have no radio nor navigation function. It takes about 15 minutes of driving until the dash notice goes away and then the radio and navigation works. Does someone else experience this and if so what is the cause and how can it be corrected? Thanks. Bob
