My husband reset the clock and since then it comes on whenever and I have noticed that my clock will just start to reset its self and then the radio will sudden come on but once I turn the car of it will not start again. Also I noticed that it will say navigation please wait then after awhile that goes away and it just leaves these lines ----- but nothing happens. I called the mercedes dealership and they said it could be electrical problems so I had my both batteries,and the alternator checked and everything was fine. Hope this was enough information thanks in advance.
my navigation system will not come on since daylight savings time. on 2007 Mercedes-Benz CLS550
