Compass Direction Does Not Show in Rearview Mirror
The button is to the left of the three homelink buttons. The compass may have to be calibrated, but those instructions are in the manual as well.

Instead, there is a small hole, through which you must insert a straightened paperclip to push. Doing that, everything works as described in the manual for pushing the non-existent "button."

I tried pushing the thing with a paperclip and nothing happened =\

Everybody: if you look at the current MBUSA website it will explain that 'compass in the mirror' does not exist for P1 cars (i.e., the optional COMAND with Nav.) The compass is on the COMAND Nav system screen. The description in the manual is a generic description for any E Class (Nav is actually still optional in any E Class.) If you have Nav then you won't have the compass in the mirror. Since just about all E Class cars purchased come with P1, they also don't have the compass in the mirror.
btw, the 'compass in the mirror' description is also in the C Class manuals, but only a C Class w/o Nav will have it in the mirror. Otherwise it's the same as the E Class: the compass is on the COMAND w/nav screen.......

Once again, cars with the nav option (P1/P2) do not have the compass in the mirror anymore. Instead it's on the screen. The description in the manual is a generic description for non-nav E Class models. It's on MBUSA's website.....
I'll agree it's redundant, but I use it when I need to see direction instead of screwing with the dash display to get to a compass display. The two displays stay almost in sync --- close enough for government work.

LOLL.... I wish somebody told me this before I tried because I did exactly what you said and the rubber thing never came back down.. I tried to get it back down but it wont come back. I don't use homelink as of now but I might have to later on.. Guess I have to go back to the dealer for this..




If one needs to re-set the compass, it's accomplished using a stand-alone button to the extreme right of all the other buttons.


That hole which shows on the overhead picture is supposed to be the point to turn it on but in fact does nothing. It is a small light to cast some illumination on the gear selector in the dark,
Pushing on it does nothing.
