| dvd navi?
I have a 2000 ML 430 with the MCS CD Navigation and cd changer..I would like to put in the DVD navigation.
Can I just remove the cd navi unit and replace it with the dvd unit? I don't need extra parts such as antenna, spitter,,,etc........since I already have a navigation in the car????? do I still need to bring it back to the dealer to reprogram? Please help.. I travel long distance very often..and the cd navi sucks... |
