Thread: Comand aps ntg 2 stopped working

Hello guys! I'm a newbi on ths forum so please be gentle.
I have this BIG PROBLEM: I have a C-Class W203-2005 NOV With COMAND APS NTG 2 installed on it. I had the battery off the car for about 6 months, and after I've putt the battery back on and start the car the Comand worked just fine. I've shut the comand from power button and from that moment I couldn't started. IT IS DEAD. Can anyone help me with this problem?

P.S. Excuse my English.

Check Fuse

Otherwise, did you have key in ignition when you installed the battery ?

The fuses are fine. Regarding the key in igniton I don't know because the car was in a service when they starteds so I was not the one to putt the battery on the car.
Is there any difference if you putt the battery back on with the key in igniton or not?

The fuse box (SAM) can break when the key is installed during battery connections.

Can you be more precise please. Is there anything that I can do at this moment to check if that's the problem?
Thank you!

You may be needing to replace the fuse on the back of the COMAND unit. It is very small and it is inside the 40 pin connector.

Take out the COMAND. Check the rear fuse.

This can happen with CD stacker

I wish it was that easy, but it doesn't have any fuse on the back.
In first place I thought it was the fuse but after i've took out the COMAND i've noticed it wasn't any fuse there. So i susspect it is far more complicated my problem then a simple fuse to replace.
