Gilly,

Thanks for the reply. The Nav CD does have a picture of an S Class on it. The Rev date on the CD is September 1999. I can find no record in the VMI of any Comand replacement.

This is weird because as you said it should work. I would expect for the system to function but just to get outdated information.

Any idea what year model the CD part # applies to?

Thanks again,
Brian
