that one really depends. I think that a couple hundred dollars, at the right shop might get it done for you, but keep in mind, that one varys by a lot. some shops will work you over the coals for the work, while some really don't find it to be that big of a deal.
make some calls. if you get a shop that says "a what?" or "why would you want to do that" or the worst "you ought to sell that thing and get an american made car", try someone else. this kind of an install is really quite common for reputable shops. they should be able to tell YOU what is entailed in the service.
