So Pioneer says that the f90 isn't designed for a cd changer. But I have a cdx-p686 which is compatible with all pioneer ip bus head units. The F90 is set up to control "external devices" so why not a cd changer. Is there some hack/ mod that would make this work or some converter box to interface the two?
My F90's set up with xm, ipod, and b-up camera.
