According to Steve from Finland I believe... Yes, you can install MB
Navigation system... it must be from ML vehicles... You just need new trim
Word of caution, don't buy used navigation system on eBay... unless there is
warranty. The reason is alot of those funky navigation units that needs
service are being sold. Repair will set you back almost to the price of
good used one or more.
Buy used or new units from reputable stores that includes warranty.
