Hey Guys I would like to know how much a clarion original headunit and cd changer would cost

pennies, they are old and sound terrible compared to later units. Why would you want one, there are far better models about, including later Clarion ones.

If you realy want one then post on the parts wanted. Check the parts for sale too as they often appear there too.

You can have mine for not much, provided a manage to get my cd's out of the damm thing.
Still, I think bockers is right, the head unit is horrible to use, and the cd changer does not seem that great, and these days new head units arent that expensive on eBay..
