My audio system has started dropping out for a few days at a time, then comes back on for a few hours.Its been going on for a week. The clock keeps adding ONE HOUR every few seconds, so the clock continually flashes the incorrect time, and will not respond to time resetting, so Im assuming it isnt a blown fuse. The radio and cd are blacked out. Air cond, trip computer and interior light all work. Its very annoying that I cant take phone calls hands free, the steering wheel controls for audio are not working.

Any ideas please?
