Retrofitting 2011/2012 Speedo in a 2008 C Class
The new screen is really impressive and it would be nice to have one installed.
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.
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

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

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.

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.
I will keep you informed relating NTG4.5
i assumed he went from the analog speedometer
for example on this car http://nl.autotrack.be/tweedehands-a.../13130114#foto
