I've connected a CD changer to my Kangoo standard radio. You just plug in to the back of your radio. I placed the CD changer under driver's seat.
It might be smarter to forget about the CD changer and fit a connector so you can use a MPEG player.
Thanks for that, where did you get the connecting cable as the one I have has a different plug to radio
I have no idea what an MPEG player is, that's right I'm an old git!
