Has anyone had any experience with auxiliary input adapters that connect to the CD changer interface on a stock radio? I've been reading up on these and it sounds like the 1998 Buick Park Avenue should have a 32 pin radio which aught to be compatible with the GMH32TC harness, which splits off the 9 pin CD changer interface. Supposedly, this can somehow connect to the Pac Aux-box or similar products (like the iSimple PxDx or the GMASX).

Will that work with this stock radio? If it makes any difference, this is the base level radio and no CD changer was hooked up from the factory.
