keys on cd player do not work

I have a 6 player cd player in my friends car. The part with 5 is not working anyway, it is not necessary. But the part buttons with a single CD player are broken and not working. only the power button works. I can't control the trip computer because the keys don't press. What could be the reason for its corruption. Is there anything like this happening to you? xmen 2015-01-18 12:22:39

Has anyone ever experienced such a situation? xmen 2015-01-18 12:23:46

Now, like this insurance, this came to my mind if the road computer button and the cd player buttons are not working at the same time and the radio is working.

I misrepresented there is probably no problem with the road computer key. I can't just enter the menu from the keys on the tape. keys do not work.

I am sure there have been problems with this problem before. Once again
