Recently bought a 2007 discovery 3, since then the radio stopped working, wont come on at all, and a couple days later so did the horn. I've checked all the fuses in the glove box and under the hood, they all seem to be fine. Anyone have any idea what could be wrong.

 

Hi Guy,
I would scan the system and see if the clock spring Error comes up.
Must be scanned by a good landrover scan tool like ICARSOFT LV2
Can bus signal from steering wheel buttons may not be making it back to central computer.
Small contacts on clock spring may have corroded.
2 hours to replace and available on ebay genuine I beleive.
