My KA had a standard cassette player. The whole section comes out. The facia kit was about �13 and a wiring was also about the same. The Sony unit was �99 plus �20 (half price) fitting. However, you can get cheaper units or more expensive ones. I guess you get what you pay for. The sales guy was helpful and I am well happy with it. Regarding a multi CD stacker - you can get these but they are very expensive. They tune in to a spare radio station selector. Also you can get CD player's cheaper on-line but I was happy to pay a little extra just to get it sorted. They fitted whilst I waited. It only took the guy 10 mins and went through all the controls with me (but setting the clock requied a read on the manual!). Good luck. Pete, let us know how you get on.
