hi there, planning on getting my first Subaru within the next 6-8 months and have looked at the '04 & '05 base Outbacks. kinda like the '05 a bit better and was wondering if the stereo can be swapped with a cd-changer controller. I'm sure it can be, but has anyone done this/know of somebody that has? Looks like the trim panel would have to be replaced also? I'd like to finally have a changer for the trips snowboarding.
