Can you get the 09' Rearview mirror with compass retrofitted in the 08' w204?
Assuming you can get the part # eventually, would it work?
My friend was drunk the other day when I picked him up and all over the place and some how he bumped his stupid head into my rearview mirror and cracked the right side of the casing...
Figured I might as well order one of those cool 09' c class rearview mirrors that have the compass built in

My friend is a local government officer and he uses his compas to send infringement notices to people who throw things out of their car. The report needs to state the details of where and how (including direction).

I too just want to know...I don't get why a luxury brand is missing so many things...a 1998 Chevy truck has a mirror and compass....a 2005 Chevy Cobalt has an MP3 AUX input...
Thanks,
Jake

Now lets talk luxury features -- automatic closing of doors anyone? I'm tired of slamming them shut, I want to close them quietly to a click-point and have them pull closed the rest of the way...
few things to make sure.
1. find out whether compass module is built inside mirror or is it getting the information from the car and mirror is just displaying the direction.
if it has built in compass, then it is easy. if not, forget about it.

2. find out if the mounting is the same. (i'm quite positive on this)
3. find source for 12v. this power shouldn't be switched, it should be turned on as you turn the key.

These connectors are marked on the control module itself where the wires go in.
Overhead control panel (without CAN) [aka cheap-*** module]
--------------------------------------------------------------
Socket
A = Power and data from front fuse box
B = Homelink / dimming mirror
C = Reading lamps
D = Rain and Day sensor
E = nothing
G = Teleaid
J = Panoramic sliding roof
I = Alarm related
Overhead control panel (with CAN)
----------------------------------
A = Power and data (5 wires)
B = Homelink / dimming mirror
C = Reading lamps
D = Rain and Day sensor
E = normal sunroof
G = Teleaid
J = nothing
I = Alarm related
No mention of a compass. Sounds like a prank.
But at least the homelink is plug and play.

the mirror i replaced was a manual dimming mirror w/o homelink.... the old manual mirror has the identical wiring harness as the new homelink/auto-dimming mirror..... it is just a matter of removing and unplugging the old mirror and then installing and plugging in the new one.... the hands-free bluetooth was unaffected by this mod
the mirror is held by a spring into the car, a tip i found was that you can compress the spring with a c-clamp which engages a smaller clip that holds the spring while its compressed to ease in installation (this will make more sense when you see the part)
anyhow, for those c300 base model owners looking to add homelink..... i was able to find a part of off LKQ from ebay for ~$80..... the mirror i transplanted came from an '08 (no compass)..... and it was successfully installed in my 2010 c300.... i tried to do a lot of research on the internet (there isn't much), but after much planning, it took less than 30 minutes to install..... hardest part was figuring out how to disassemble the overhead control unit, turns out it swings away on a hinge to reveal all the wiring... had i known that in the beginning the mirror would've took less than 10 minutes to install....
