My 2003 E200K rides very good. However, for some time I have not been able to activate the MAP and SERV display on the Comand APS. Nothing happens when I push either of the buttons. Anybody knows how I can get these functions back? Otherwise it seems like all functions are ok on the Comand.

 

The problem is now solved. I had a STAR diagnosis which showed that there was software problems with the Comand APS. Mercedes replaced the unit with a brand new without any cost to me - priced to NOK 60000 (USD 9500) in Norway. The guarantee was out more than a year ago. Real great service by Mercedes.
