This was a complicated option as it involves a colour screen head unit, an Audio gateway and a separate navigation drive.
On higher specced cars this also meant linguatronic, phone, TV and Cd changer all connected onto the fibre network.
However, the serial numbers of the comand units are all checked and coding these units can only be done online via a supported DAS/Xentry system.
If its come from a suburb of a major town in Germany or a car park near an attraction such as a theme park or a forest/lake or close to an airport, draw your own conclusions as to its legitimacy.
Brand new comand units show the location of the Mercedes factory.
We know of at least one customer who bought a Comand from a well known auction site, took it it to his local dealer to have it installed and was told the unit was stolen.
They promptly kept the unit in order to return it to the rightful owner.
This occurs when an NTG 2.5 comand with recent firmware on it is removed from a car and then installed into another vehicle. We can do this but unless we are absolutely sure of the source of the comand unit itself we wont.
Mercedes are now storing serial numbers of comand units and cross referencing these during installation.
One of the pitfalls we have seen is customers sourcing their own NTG 2.5 comand and plugging it straight in to the existing Audio-20 loom in their car. It is imperative that you use a good loom converter to adapt your cars wiring.
Another common issue is that of the comand coming up 'Auto theft protected'.
This system is good when it works but if any single component on that fibre ring fails then they all stop working.
