Hi, I have a 2002 Dicovery II. My sunroof leaks from time to time and now it has dripped onto my radio. Now the panel controlls and the stearing wheel controlls for the radio do not work. I have a CD that is playing and I can not change the volume, switch songs or even turn the thing off all together. Any one ever had this issue? Does it just need to dry out or is it done for?
