Hey guys, I have a 2011 facelift cu2 with about 65k's on it. Yesterday after I washed the car, the radio unit buttons suddenly stopped working including the steering wheel controls. So its now stuck on 1 radio station and none of the buttons on the radio respond even the on/off button. The only thing that works is the volume dial. Air/con and heater is fine.

Has anyone experience a problem like this or know how to approach this issue?

Any help/advice is greatly appreciated!
