Is it possible to retrofit one of the new color screen speedometer into a 2008 C Class?

The new screen is really impressive and it would be nice to have one installed.

I'd assume you'd have to program it with STAR. Even if you program it, I'd assume some of the selections wouldn't work because more features have been added that are controlled from the instrument cluster for the face lift model. Maybe someone with more experience can chime in on the subject.

Hello,
Does anyone have more info on this?

jay_007

I asked the same questions little while ago and was informed you can but very costly plus you need a brand new speedo which hasn't been assigned to any vehicles yet, only way to get 1 is from MB the you need to program it in with STAR. Some1 here with more knowledge then me can give you more detailed info.

CrisT

Thanks for the answer. I wanted to know how complicated it is to install the new screen in the dash, as it's easy to find one in a damaged car.

I don't really mind not having it, as the only things that I really want are the comand system, the Harman Kardon sound system, the new 3 spoke steering wheel and maybe a few other stuff that are easy to install.

I have been told you cant fit a speedo off a another car, it has too be a brand new item which hasn't been assigned to any vehicle so no point looking getting 1 off a damage car/salvages.

There are some videos or pics (cant remember which 1 it is) in this forum on changing instrumental cluster which includes taking speedo out.

Just search under instrumental cluster

I retrofitted the facelift speedometer in my pre facelift 204 one year ago.
It's also possible to enable the AMG menu in non AMG speedometers.

Ok, that's all you're going to post? Tease :P Give us the specifics please.

Minuszeit

The facelift speedometer fits perfect. You just have to replace the upper part of the facelift speedometers housing against the old one. That's all.

Encode the speedometer via SD in developer mode.

The safe way is to use a brand new speedometer. A new one will assume the mile/km age of the car. A used speedometer will not, just ------- appears. In this case you have to desolder the Eeprom and flash it. The same procedure if you want the AMG menu in non AMG speedometers. But this is something for experts in electronic.

If you use a new facelift speedometer and encode it via SD developer everything runs fine without any promlems.

This is awesome news.

I also retrofitted some parts of the W212/C207.

- Comand headunit NTG4
- Air condition panel
- Memory switches of the front door control panel
- Front/rear overhead control panel
- Nappa leather armrest
- Nappa Airbag of the R231

That's cool man. Why did you upgrade the head unit?

Minuszeit

Thank you.
I retrofitted the W212 headunit because of its bluetooth streaming ability and because of its ability to read and import the cells phone book via bluetooth.

aznmode

That's what I figured why you upgraded, but you said NTG4 so I was confused. So you updated to NTG4.5 from w212. The A2DP is what I really liked on the NTG4.5. This might have to be my next mod. Was it just a straight swap? Did you have to swap the screen too?

Minuszeit

It is a NTG4 headunit, you can see the PCMCIA slot. NTG4.5 has a SD card slot.
The bt streaming and phone book ability is a feature of one of the latest firmware updates.

aznmode

Got it. Thanks for the correction . Is it a simple swap? Being able to stream music from my phone and read my text on screen would be great.

This was the last thread I asked in regards to this back in May but never got a response from anyone.

Yes, you just have to shorten the faceplate.
Remove W204 headunit, install 212 headunit and thats it. It is really a simple thing.
Btw, it is also possible to upgrade to NTG4.5. I developed a converter so that one can maintain the W204 pre facelift display. Just one/two minor shortcomings have to be fixed.

Just went to my car to show you the bt streaming function of 212 NTG4.

aznmode

Thank you very much for the information! I'm good with dremmel so shortening the face place is going to be easy. Now the only problem, I don't have a way of upgrading to the latest firmware. Hopefully I can find a disc on ebay.

Please let us know about the NTG4.5 upgrade also once you get it fixed.

Minuszeit

Every MB dealer should be able to update firmwares. The updates are part af the Telematics DVDs the headquarter send to the official local MB dealers. It's not like that in the US resp. North America?

I will keep you informed relating NTG4.5

aznmode

Unless it's a necessary update then I might be able to get my dealer to do it.

Minuszeit

I'm confused.
Here in Germany you tell your dealer that you want him to do the latest update and he does. It's about 75,- Euro/100 USD.

aznmode

Correct there is a fee but not sure how much. I thought you meant getting it done for free.

Doa

don't you need the steering wheel with extra buttons and a new steering column module before the digital speedometer works?

Minuszeit

No, it's unnecessary to upgrade to facelift steering wheel and column if you want the facelift speedometer to run without errors.

Doa

ah but thats because you go from digital to digital so you already have the steering wheel with extra buttons etc.
i assumed he went from the analog speedometer
