again with the Mr. Capitalizes Everything... wierd.
ebay may or may not have anything for you- I tried for 2 years to find a cd slave unit that will work on my (our) car, and had very little luck. Honda has stopped making them, and there were not a lot of OEM units.
crutchfield carries an aftermarket manufacturer of the 1-disc slave unit and the 6-disc trunk changer, but they are rather expensive.
Good luck finding one, and if you find a supply, let us know!
