Trying to replace my faulty CD/radio system. The radio works but sound is not outputted correctly, but when CD is played everything is good. So, I was thinking about replacing it with a newer model. I was looking at part number 86120-33040 which came in some of the 94+ Toyota. The car is my 93 Alltrac with the system 10 unit. If I remember correctly as long as the plugs match it should work correct minus the 90-91.
