question regarding 2003 500ML stereo

[canuck699]

I am looking to find out how hard it would be to put in a factory nav and telephone into a 2003 500 ML. its got the head unit already in place, but when i press the telephone and nav buttons it says the modules are not installed. Anyone have any suggestions where i could grab them, and how hard they would be to get in place?

Yes the unit already have the telephone button in place but probably not activated. You need to install a bluetooth adaptor and program it to make it work

You can replace the drive or swap the MCS. You'll also need the antenna and disc. By swapping the drive you will not be able to play a CD while using the nav so you may want to look into adding the CD changer. I'd also try to look for a DVD drive as the CD nav discs are no longer available IIRC.
