I have a 04 E500 with Comand DVD Plus (without navigation) Can this be upgraded to GPS by adding The Dvd player in the trunk?
Lucky Me I also have a useles phone system, is there anything I can do for it?
Thanks,
Gary

 

My E350 '05 also came bare like yours but I did have the GPS and TEL buttons on the dash. So, I took a chance and bought the parts on eBay and now I have: GPS, Phone and also Voice Control These parts assume that some basic wiring for these options is already in place (i.e. installed when the car is manufactured). Unfortunately the dealer is typically of no help here, as I was told (even after they looked up my VIN) that the wiring was not in my car when it obviously was. My opinion is if the buttons are there, then the basic wiring will also be there.

 

Thanks, I sure get lots of opinions!! I was also told My phone could not be used!!
Amazing the number of members read this post and didn't contribute!
