Were there any fault codes stored when the garages did their diagnostics check?
What exactly did these two independent garages do with the vehicle?
Thanks
The first issue you will face is the Anti Theft message which is displayed when installing a unit from a donor vehicle. This is easily rectified if there is a PIN stored, i can check this from the serial number of the unit. If you can post a picture of the sticker i can check.
Once that is done...
The first Screenshot shows that the head-unit you have is only TO chassis F122951. Yours is F175364
Second screenshot shows what head-unit is based on your VIN.
Who has told you that it cant be coded?
Joined the forum a few months ago but forgot to introduce.
I'm from Derby and do work with Mercedes cars/vans. Have Mercedes STAR and online access.
Happy to help anyone on the forum.
This is only available through MB. If it is the original unit you can obtain the code from the Dealer by showing your V5 document. If it is a replacement unit MB Dealer will not help you at all. We can check the mercedes servers to see if a PIN is stored for your unit.
