Customer Question

I have a 58 plate C200 Sport Kompressor Estate with Sat Nav. For some reason the spinning Sat Nav knob by the gear stick wont allow the map scale to be altered or move curser across the screen. Can you please assist?

I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

Hello, welcome. My name is Mike, I will do my very best to
assist you with your question.

Are you getting any kind of error message?
Customer: replied 4 years ago.

No error message. It is just the spinning function that doesn't work. It is only a real issue with the map scale as it is stuck at 0.2 mile and you can't zoom in or out

Expert:  mike_a_mechanic replied 4 years ago.
Ok this issue normally happens because there is a fault with the screen of the system. I am also a warranty inspector and I have inspected this issue before. In some cases the screen has to be replaced and other cases the system can be reset. To reset the system you can remove both negative and positive battery cable ends and leave disconnected for 10 minutes.

Is disconnection the battery to reset the system the same as the reset on the actual screen choice? Interestingly, I've just found that the voice recognition allows the map to be zoomed in or out!!

Expert:  mike_a_mechanic replied 4 years ago.
No the disconnecting of the battery is considered a hard reset of the system and is different than on the screen.

I've taken a quick look in the engine compartment but can't see where the battery might be? Can you advise

Expert:  mike_a_mechanic replied 4 years ago.
The battery on these vehicles is located in the boot and sometimes under the rear seat,most of the time in the boot.
