yeah, simply adding an aftermarket deck can be difficult in the SHO. it has multiple amps to run the subwoofer and interior speakers, and interfacing the amps with the new head unit usually requires an extra harness of some sort at an extra cost at places like best buy / circuit city. the add on changer isn't a bad idea. but don't forget that RF modulation isn't the best signal transfer, and you'll basically be losing a good amount of the quality of your cds over the radio frequency. but the changer would be very convenient. in most cases, those controls on the dash won't work...actually in all cases i can think of, unless you're deck has a port for a wired remote like some sony's do, and an adapter is made to make them work with it, or you have a stereo shop custom wire it up, which would probably be really expensive. if you go to a stereo shop there is a good chance that they are going to try to get you to upgrade everthing, which in some instances isn't a bad idea, however i wouldn't recomend having circuit city or best buy do that type of work, go to a real stereo shop.
