Mercedes E class W211 diagram of the storage box under the radio

In Mercedes E class W211 2006 (after lift) the electric storage under the radio does not work.
All functions on its front work properly (heated emergency seat buttons, etc.).
Radio is not original (Android).
Apparently, the storage box opened normally on the original radio.


Maybe someone has some electric scheme for connecting the installation of this panel?

Hello,
This storage is a place for a cd changer, the mechanism is controlled by the original radio after receiving information about pressing the button on the panel.
I once saw on the forums a solution with a direct connection of the opening motor through an additional switch and relays, I know that the diagram is not readable but I have nothing better.
Unfortunately, there is no access to WIS at the moment so I don't have the module and cassette diagrams.

I hope this helps.
greetings

This scheme is simply a change of voltage polarity (+/- to - / +) on the output terminals of the system - controlled by a rocker switch.
The additional system would have to directly control the "engine" of the clipboard drive.
It can also be used e.g. to control an electric window motor.

I am interested in the "as original" solution, i.e. control using the original button on the front panel, e.g. like this:

"behind the storage" is visible "some electronics", which probably implements the logic of controlling polarity change using a monostable button on the front wall of the panel.

There is an AVT kit that can do this, the drive shuts off when it detects a rise in motor current above the set threshold.

CameR I have the same problem I bought the same radio. Have you already solved this problem with this clipboard?

The topic is still not resolved, although I must admit that I did not think about this storage again.

Hello, does anyone have time to get hold of the topic notepad

Is there any possibility to send a link to the AVT kit? I also changed the radio and I care about the factory button

Where can I find something like that? Do you have a link?

On ne555 I did something similar to the last layout from this movie: https://www.youtube.com/watch?v=k4k25-rT0t8

Moderated By CameR:

Can you explain what the 555 bistable flip-flop app has to do with the w211 clipboard upgrade?
Here, you need a system that gives an impulse of about 2 seconds and reverses the polarity with each press of the button to alternately "close" and "open" with one button - that is, to change the speed of the motor.

Reg. 3.1.11. Don't post messages that add nothing to the discussion. They are misleading, dangerous or do not solve the user's problem.

Hello, I am the owner of the w211 for a long time and I have a non-original radio, has anyone managed to do it?

I explain to my Dear Colleague Moderator, I base the operation of the button on this system, plus simple polarization control on the next 555, as here: https://youtube.com/shorts/-JNucVBqv-o?feature=share , only with fixed resistors and a few additional elements and we have a beautifully functioning clipboard button. Of course, this can be built more simply in digital technology. I built it and it works.

Hello, I managed to diagnose the engine for the panel works after connecting the entire set with the storage box it stops working, it hides and then nothing
