Conversation Between studman and Bri974

Hey Studman, you seem to know your way around the Bose systems, so I have a question for you. I have a '91 (3rd Gen) with the Bose system, and the head unit is shot. I wanna replace it with a newer ('02-'07) HU with integrated in-dash 6 disk changer. Any idea if this will work? Any wiring harness or fitment issues I need to know about? It would suck if I bought a new HU and then found out it won't work and/or fit. Thanks in advance for your time and have a Happy Birthday!
