Clean kit, looks and functions like stock
2004 Mazda RX8
This kit fits very well, and the microcontroller box interfaces perfectly with the climate control system and stock LCD in the dash. The wiring to the radio is well labeled; however, some of the wiring is reused on the interface to the controller box. The reused wires have labels like "left speaker +" which are meaningless. The instructions explain the wiring for that connector via colors, but it is a subtle point and left me confused at first. The instructions should be more clear, or other wiring should be used. Also, it would be helpful to expand the radio install instructions to clarify that the dash vents must be removed to allow the radio to be mounted under their mount tabs. Still, it is a great kit, and I'd buy it again or recommend it to a friend.
