Hi, The head unit is a Sony affair (about two years old) which plays mp3's I've burnt to a disk. I think your solution saves money on disks! I also think there is an interface available to facilitate use of steering wheel control, which is more money than it's worth considering my arm is long enough to reach stereo!! Still not got round to horn problem, although know it works when you apply 12v across it, directly. Tested this while GEARBOX was OFF!!! Replacing shattered release bearing which had allowed release fork to swing into pressure plate springs - Thereby banging a bit before locking engine!! What fun that was £105 for clutch kit + £100 bung for fantastic brothers help and spacious heated garage + weekend swearing at car. It's great now though, :rolleyes: Apart from the leaking pipes we found . . . oh well . . . MOT not till March . . .
