On my 2000 w220 the date is grayed out and set to 1999. I cannot cursor to the date to change it. The location is correct at mt std time. but daylight savings time is wrong and date is wrong. not sure what to do.
Any suggestions.

 

Hi. this just started happening to my S430 (W220). Well i mean i just noticed it. The problem with mine appears to be related with GPS rollover week earlier this year. did you get any help in fixing this?

 

moved to W220 forum...

 

I did find a way to set it manually in my owners manual. But, the GPS will not change it automatically.
