Does anybody know how to get a Navigation antenna for a 2001 Mercedes Benz ML320?
I had the var for three Years and I have not used the navigation system still.

For those that have the MCS without integrated telephone or the navigation. how could I go about buying and installing these things myself.

I could perfer not to use the motorola phone that dealers sell you and integrate a phone that has car kit abilities ie. muting, uses stock microphone, speakerphone.

Navigation: clairparts.com has the mcs navigation for 1500$ but the picture is of the unit with LCD. that's what I already have. I just want to activate the nav functions by buying whatever is missing to make navigation/voice active.

The system already comes with an antenna.
