RE: 00 ML Navigation - Operation?
From reading ebay ads, would appear that 2002 and up do not need a separate antenna added but 2001 and prior have to also add the GPS antenna to make it functional. So if you are going this route you will also need to find an antenna. There are suddenly several navigation cd units on ebay search "mercedes ml navigation" and you will see 3 or 4 of them. Of course if you are in a rural area such as Arkansas, the navigation unit only knows state and federal hiways so it isn't all that. My Lexus even knows driveway 911 names, but my ML can't get within 4 miles of my house. Hopefully they will get on the ball with city mapping before these vehicles themselves become so obsolete no-one will care if they have nav or not. If mapquest, yahoo, and toyota can get street maps, why can't Mercedes???? Disgusts me. Anyway, good luck with your nav project. Sounds like an easy install if you get the cd nav unit and the antenna.
