I am selling off my RDZ-755z head unit and dedicated 6 disc changer. I really like this unit, but does not support the surround system I am currently upgrading to in my car. The unit itself has front, rear, and subwoofer dedicated pre-outs. 40 watts X 4, magi-tune for very good FM tuning, full function one handed remote. I still have the box that this goes in as well as the paperwork. The changer is a 6 disc dedicated which the head unit controls. It also memorizes 100 cd titles and 50 radio station titles. It also comes with 2 cartridges. The changer has a few cosmetic scratches (damn jumper cables) but overall the unit has been pampered. Best of all both are still under Best Buy's 4 year warranty. Retail was 400 + 250 for the changer. Asking $200 + shipping.
