I had the var for 3 Years and I haven't used the navigation system yet.

The system already comes with an antenna.

For those that have the MCS without integrated telephone or the navigation. how would i go about purchasing and installing these things myself.

I would 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 is what i already have. i just want to activate the nav functions by purchasing whatever is missing to make navigation/voice active.
