W211 command not working
I would really appreciate if somebody could help me please.
I have recently brought w211 2006, facelift model.
Great car but it has an issue with command unit. It switches on ,shows logo and then goes off.
according to the previous owner it started when he was changing the battery.
I've done a lot of research on this but it looks like none of it applies to my car.
I have checked fuses, purchased fibre optic bypass...but the issue is that there is no navigation unit at the back, this car does not have a cd changer and when I've tried to connect the bypass to the voice module, I've unscrewed that plastic lid in the bottom of the boot, but there is nothing there at all, it's completely empty

I've also bought exactly the same command unit from ebay, connected it and its exactly the same issue.
Also that little compartment just below command unit doesn't open, not sure if it is linked in anyway.
i would really appreciate if somebody could guide me in the right direction please
Thanks

Yeah, I thought so, but it still has a navigation button and also comes with navigation dvds. Does that mean that the navigation is built in into the actual command unit?
Also would the aftermarket unit work if the audio gateway module is faulty?
Thanks
