Hi,

I have a 2004 CLK 320 (Without Command) and the clock changes twice per year based on the older daylight saving time standards (current standards minus 1). We in Arizona do not participate in DST so I wish to turn off this feature. The owners manual states that the DST On/Off choice displays after changing the minutes. This is not the case with my car. The DST On/Off screen does not display at all. The techs at the dealership have not been able to solve this problem. My thought is that an e-prom was updated with invalid code but that is only a guess.
Any ideas?

Thanks,
Jack
