I have a 2000 S500, and a few months ago, the navigation stopped working. I bought the car about a year ago and it (navigation system) was working fine until earlier this year. Whenever i push the NAV button, the screen either reads "No Navigation CD, Please insert Navigation Cd" or "CD Reading Error, Please change CD"--the navigation cd is in the system while it displays these messages. I have also used another navigation cd and the same messages appear. Any suggestion as to what i can do to fix this problem? Thanks.

 

I have the same exact problem on my 2000 S500. Does anyone know if this is repairable without replacig the entire navigation unit? I tried all my CDs and they all have erros and cannot be read.

 

is there a way to reset it maybe?

 

MB has the worst nav,sat,radio system I have the proof my system started doing the same thing and it basically broke down the dealer wants about 6k !! in NY for a replacment unit
