DIY: 06+ W251 Radio removal - instructions with pics
(Click on the picture for a full size image.)
Here is a pic of the unit.

Insert a clean tool (I used a 90° hook tool, but you can use a flat head screw driver). Make sure it's clean, as to not stain the leather. Insert the tool at the location shown in the picture below. There is a clip that will release the HVAC once you press on it. It it easy. No force required.


Do the same for the right side.

Take out the HVAC, and remove the plugs.


Remove 2 Torx-20 screws (highlighted in red).

Pull straight down on the 2 silver pieces. This will release the radio. Don't pull too hard as to break the piece, just enough to release the radio.

Here is what the silver piece looks like, and how it works.
This is the piece up.

This is the piece down.

Pull the radio out. It's easy, no force required.


Unplug the radio harness. All the plugs are connected to one main harness. Pinch the clip, and fold it out. This will release the harness. No force required, it is fairly simple.


You're done!
If anyone has any questions, feel free to ask!

Can you give more detail on the backup camera? I have an '06 with Nav and was told by the dealer that I could not put a camera on it. I really would like to have that camera installed.
I'm using a module that integrates with the factory radio, and a small camera. What the module does is override the video display, and plays any video source (camera, dvd player, etc...).
I'm installing the camera to the left of the third brake light (to be symmetrical to the washer nozzle). I'll post some pics throughout the next few days.

Fantastic job! I look forward to more info on your effort. I want to install a backup camera on my 07 500.
What harness are you using?
What camera are you using?
Are you mounting to the factory spot above the license?

Thanks.
I picked up an 06 R500 and looking to do this as well. Please post up the parts (actual part numbers would be great) that everyone is using for the install. Also, does anyone have any updated pics of the install and connections at the command unit? TIA

You start by removing the A/C panel. Now I don't actually advise using a Swiss army knife, but it serves to show where you have to go. Insert a slim blade (or even the correct tool!), feel for the clip, push, wiggle, and pry gently...

...and one side pops out. There's an identical clip on the other side, but I didn't have to work on it; just a gentle pull, twist, and wiggle on the A/C panel and the whole thing popped out.

Here's a couple of closeups... above, the clip you're trying to release. Below...

...the moulding it locks into.

With the A/C panel out of the way, you can see the two silver clips that secure the head unit. Loosen the Torx screws just enough to slide the clips gently down, and the head unit will just slide out.
Refitting is the reverse of removal, when refitting the A/C panel it's best to put the bottom in first, and get that aligned before you push the top in and lock the clips.
Hope this helps!
