Citroen RD4 buttons not working
I own a C5 Exclusive break 2006 Phase 2 with a Blaupunkt RD4 N1 radio. This radio is the interface between me and on-board computer with acces buttons for menu, navigation arrows, and more. Any buttons of radio wont work except on-of switch. The radio is working fine with whels command (i can change the source, volume and tracks or radio station). Anybody can help me?

I opened up the face plate too, on the back of the PCB there were some contacts with black rust and they expanded over other contacts quite a little so they were in short circuit. Just cleaned them with a mildly damp cloth, the PCB came back to its natural green and now it works, I can access all the vehicle functions.
