the cd changer in my car is a universal item, pioneer cdx-fm that connects via FM signal which is a very mediocre set up to say the least.
is it possible to get a CD changer to connect directly to the original head unit and be controlled by it.am thinking of getting the SOS , OEM to aftermarket harness and installing an alpine pdx4-100 amp with alpine spx 17 ref speakers. any advice greatly appreciated(and needed) as the installer hasnt a clue about the OEM set up
