Hello - not quite sure what you're asking in regards to the nav and side mirrors. The navigation is built in, like you said; so the front display should allow you to control everything from there. I'm not familiar with a dvd setup in the trunk - do the backseat headrests have screens built in? What are you looking to replace?

Im sorry I messed up. Im not clear about the nav system. All I know is the display (where the radio is all that stuff) has a nav setting but it says nav not available. I have seen some post on youtube for my year model they show a device in the trunk (left hand side) that ya put a nav dvd in. I don't understand that at all. The side mirrows best I know are heated, have memory controlled by the door switch. They have turn signals in both. I see on ebay, amazon and peach after market mirrows way to expensive, looks to be 2 different models also. w211-w212 something like that. I have all the books came with this car but not much help. Hope ya can help. Was a shock see one side mirrow priced from $160.0 all the way up to $300.0.

Early 211 NAVI is an add-on. You can buy the installation kit including DVD drive. The drive is installed on the left side of the trunk. The head unit will need to be programmed following installation..........
