kenwood KDC-W7031 sell or swap +

i have here my kenwood cd/mp3 player that is fitted in my astra, it has a motorised flip face with 3 tilt angle options for a better view of the colour screen, its 4x50w with front and rear pre-outs and is multi-shuffler compatible, i dont know much about the other functions or capabilities of this but will leave in the car so can be seen working, it has a great sound and a few different animated screen displays but i would like to fit my own cd player that i know how to work, i would consider a swap for a nice rear exhaust to fit an astra mk4 estate.
