03 1.0 Playing MP3s in a Yaris with only a CD play - piggy
I have recently solved this problem with my car radio by getting a cable from the UK agents of it`s manufacturer. AFAIK,your radio needsto have an auxillary socket at the rear.This is normaly used to run a CD changer. If it does not have this Aux facility then it`s much more difficult.
Try going to the ICE section of the Toyota Forum for advice,or try e-bay where they have dozens of this type of connectors.My cable cost £8 and works well.
