My 2016 GTS command display won’t come on and the dealer says the control unit needs replacement. Does anyone know the MB part number? Thanks.

MB Oem Parts website says its Part #

205-900-66-34-80

$2140.26

Look on Ebay etc with same Part #

ddtung

Thanks for the reply. The display panel is functional, what is needed is the control unit for it. It is one of the other parts in your diagram

BBS63

That part # is for the Control Unit not the display.

Hi,

@ BBS63
This partnumber have to much digits. Mostly A with 3-3-2-2 Digits

@ ddtung

You mean the invisible headunit? (comand)

For the GTS there are a whopping 114 (one hundred and fourteen!!!!!) different part numbers for the head unit.

With your FIN you get exactly where you want to go :-)

Since you have an Edition one, you can limit it a bit.

This part numbers should match. -> USA / AEJ 14/1 / Single DVD


A205 900 83 17 replaced by: A205 900 39 19

That part number I posted I got from MBNA parts website.
Even googled it just now and it has same result for the Control Unit which is what he is looking for.

Stenzel I was given the part #MA2059006834 by the service department in Hong Kong.

i also found the part #205900663480 from USA MB parts suppliers.

Should be the same part?

ddtung

The control unit looks like this

ddtung

VIN is WDD1903782A004305

Stenzel-Germany

Hi ddtung,

Hong Kong? OK. that's something completely different.

According to your VIN you have the following important codes:

3U4 HEADUNIT ASIA-CHINA/KOREA/TAIWAN/HONG-KONG/MACAO
347B LANGUAGE INSTRUMENT/ HU - TRADITIONAL CHINESE
814 DVD CHANGER

Your Car is built on July 03, 2015


Then this head units should fit: (Used? maybe you need Softwareupdates)


This head unit was factory installed as new vehicle (New, no longer available) A205 900 81 21

Replaced by (New, no longer available) A205 900 48 22

Replaced by (New, no longer available) A205 900 79 23

Replaced by (New, no longer available) A205 900 58 26

Replaced by (New, no longer available) A205 900 50 29


​​​​​​​Replaced by (New available, appr. 2600 USD)

A205 900 68 34

This is the last one suggested by your dealer:
A205 900 68 34 is also installed in the GLC.
Is also the 3U4 Asian version and also with 814 DVD changer.
Might work with an SW update. But should cost around 2600.- USD

Wow that is impressive! Much appreciated.

Please correct me if I am wrong. If I can get any one of the 6 #s you mentioned or the one quoted by the dealer it should work with a software update.

I will start my search for the most cost effective replacement and take it to a friendly dealer to install/ program it to fix the problem.

Again thanks for your help.

Hi Victor,

I cannot give you any guarantee for this. I can only pick out the numbers for you. I can't check whether these fit 100%. There are already different generations of the HU. Most of the time the part numbers differ only by software. It was no joke that there were 114 different versions for the GT in 2018. And the brand new ones aren't there.

The early HU (Harman, especially with a DVD changer) often had problems. (But rather with the changer mechanism)


Stupid question.
How sure are you that the HU is really defective? What has been checked so far. No display can have several causes. (For example, there is a fuse on the HU, without disassembling you cannot get to it)

Personally, I would try to find the exact error first. If irreparable, get a used, newer number. Or just a really cheap one. The used market is not that big. But thanks to the internet, the world is small.

Second hand.
Remember that you will also need the device code (anti-theft protection). Without this, the HU is not worth that much. (a hacker can do this :-) )


Best regards

Stenzel.

Thanks for the reply.

I sent the car to the dealer and they connected a working HU to the display and it worked. So they concluded that the HU in the car needs replacement. That’s how they fix cars these days!!!

I found a supplier in Germany that sell A2539003206 for $1100 + shipping. They don’t have A2059006834 which the dealer recommended.

i cannot find any used parts on eBay at the moment.

I will keep up my research and search before buying.

Any further info would be appreciated.

The weights of the 2539003206 part is 1.4 kg while that of the 2059006834 part is 2.9 kg. This is very confusing. The 205 part also costs almost 3 times as much.

Stenzel-Germany

Hi ddtung,

You were right about the weight. That gave me no rest.

Unfortunately, I have to tell you that I had a transposed digit. (was late :-))

Have corrected my post so far. Now it's 100% right.

Please delete your copy, as the part numbers here are incorrect.

From early to late version:

A205 900 81 21
A205 900 48 22
A205 900 79 23
A205 900 58 26
A205 900 50 29
A205 900 68 34

Maybe you find one in Asia.


As compensation: :-)
