it came with the single CD, no radio controls My question is this, if i locate and buy an 05-07 JBL or 6 cd unit will it work? I know i can pretty much forget the steering wheel controls, but would either of the upgrade units work? Does anyone know if the JBL or 6 disk is much of an improvement over what i have? I really hate to go aftermarket because most of the ones i have seen look sort of like an afterthought. I will be switching out the speakers as well.
