Hello together… A friend has an Omega 3.0 year 2001. He has the NCDC 2015 Navigation&Co. Since yesterday he does everything he wants… From time to time sounds out and again nothing. The monitor is white tightened and does not react either. The operating ropes on the steering wheel also do not always work. We have the impression that it might have a wobbly contact. It could also be a software problem. So I don’t know. have looked around here in the forum a little bit. without success. I have pressed the Clear button for a long time. It went out and on again very briefly. Battery has also been jammed out once. Nothing has changed. Does anyone have ideas or experiences what this could be????? On other things we have to expand it and see if anything has solved ;-)) Do you have a disassembly/installation instruction (with pictures of course)for that. Thank you in advance.
