I would like to replace my OEM Bose Cassette stereo with the equibelant OEM Bose CD stereo. My Bose Cassette Unit has a Slave CD Changer. Will the OEM Bose CD head unit control the cd changer. Both units have the Aux input. I have read on line that the CD head unit will not control a cd changer only a slave cassette player. But I have also read as long as the plug is correct the Aux input will control either a slave CD Changer or Cassette. Below is the type of radio I would like to replce my current unit with.
