Hello everyone , I’m working to upgrade on my w221 s Class 2008 model the seats with panel and the command system from NTG 3 to NTG 3,5. All this because I buy a used interior set AMG with massage , dynamic seat and rear entertainment screens from 2012 model car. I have success replace the NTG 3 with NTG 3,5 command , the seats with the panel and I replace in the trunk the air pump for the massage-dynamics seat.
I pass the harness wire for the rear entertainment and connect it on the seats ( power and signal ) and the rear dvd device. The only problem is the rear display are not working, I’m try it to turn on with the remote control but not response. Notice I coding with STAR enable fond entertainment, AVS , Split View. and I replace on the trunk the air pump for the massage-dynamics seat. Anyone have any idea why the car can see the rear entertainment??

Hello to everyone, finally after couple of weeks I retrofit Ntg 3,5 command + dynamics seats with heating - cooling + massage and rear entertainment on my 2007 Mercedes w221 S class 350 cdi.
The project was not so complicated to work all the module units in my car.
So that is possible with used parts , if anyone need help I’m available for informations and advise.

Yes this will be fit and work but you need to buy also a used head unit command and screen ntg 3,5

Aha, thanks for that!

I then think it will be to costly, maybe i wil look for parts to repair my dynamic seats because this is what is broken.
