I've got a Ford Mustang GT with the Shaker 500 audio package, I really like the 6 CD changer being right in front of me but I'd really like a nicer head unit. I was wondering if anyone makes an aftermarket double-din CD changer that would be able to work like a factory unit?

Another option I'd be interested in is a cd-rom changer. The closest thing I've found is a Pioneer DRM-6NX but it's got a SCSI interface, does anyone make one that's USB and somewhat slimmer?

If there's nothing I might just end up keeping the stock head unit, but with all of the cars that offer a 6-CD changer you'd think there'd be at least one aftermarket solution that replaces the stock radio. I really don't want an external unit that I'd need to make room for in my car.
