looking at this radio for my truck

If you want to retain bose, onstar and RAP then you need the interface. If you are adding subs then I personally wouldn't keep the bose. You can easily bypass bose with the harness inside the dash that is clipped to the subdash directly behind the A/C controls. You can use the GMRC-01 by metra if you want to keep the door dinger(or lose it by clipping the wires to the internal speaker in the GMRC-01) and RAP, jsut hook it to the harness you use to bypass bose.

Just about anything Kenwood is good quality. If it were me I would go with ipod before a cd changer.

agreed, I didn't notice that the other was used until now. I personally wouldn't buy used stereo equipment unless I knew the person I was buying it from.

Roger that and also just a small experience from that Kenwood deck he linked to... Ive had 2 friends with that deck previously, the flip down controls of the head unit stopped working so they could only use the remote to navigate. Even though only 2 people, just a word of warning.
