The colour display for the sat nav etc only works if you keep twiddling one of the dials. The radio/cd work but it is annoying to have a flashing screen. The voice of the sat nav is a very loud screech and is unusable but if you were patient enough to keep moving the dial the information is correct. Is this likely to be a display problem or the computer in the boot. It has had water in the boot before when some of the trim was damaged.
