I am new to this board. I purchased a used 2005 C240 last year, it is a fantastic vehicle and I have no problems with it. My issue is that I cannot reset the clock and I have been driving around with the wrong time for a while. I checked the owners manual and it doesn't appear to be correct for my car. I am able to get as far as selecting the hours (12 or 24) and then I cannot access the next step of actually changing the hours and minutes. Can anyone please help??
