Stock 460 slave cd wanted / HELP

[HorsPowr]

I have a stock mach 460 sound system in my 95 GT conv. 2 things - the first is the cd player is crazy. Rarely reads a cd or skips to the next song without ejecting. - the second is a weird ignition noise that is sometimes, not always, present upon turning the ignition/radio on. Does any body have a slave cd unit for sale that WORKS? Also whats the deal on the 6 disc in dash cd changer? Is that for a later model setup? wil it work on an SN95?

Thanks for the help.
