If you opt to do the work yourself, there are plenty of us around that would be more than willing to guide you through the work, but I really don't recommend replacing that 6-Disk Din-Sized changer with anything but a storage pocket. In my experience, cramming all those moving parts in such a small space is just asking for trouble. In fact, 6 CD's doesn't really hold that much data anyways. If anything I'd replace your in-dash head unit with one that reads MP3 disks and just burn your own CD's - you'll be able to cram more songs on an MP3 disk than 6 full standard CD's anyways. If you do get a changer, get one that reads MP3's and you'll be able to store more than a thousand songs.
