You have to go to a sound shop and they will have you saign a waiver. However it cost about $900. I knew this in advance so I got the plain radio and bought an aftermarket unit for $2500 and then you can put it in any car you want. when you convert the vette you can't take it with you. Now if I get rid of the vette but will never happen I can reinstall the factory and put it in the next car. I think Circuit City or Best Buy is doing it now.
