Hi, new to the MB world, so I have a few questions I would like to get answered. The E350 that I bought was not equipped with Navigation nor Xenon headlights, but I would now like to add them.

How would I go about adding Navigation to the car? OEM Navigation I mean. I already have the head unit with the screen, but when you press navigation, it says unavailable.

Also, if I were to add OEM MB Xenon bulbs, ballasts, and ignitors to the car, would I have to switch the headlight housings out itself as it's a diff projector or not? Thanks in advance.
