would you mind going into detail.. Sounds like what the soundgate aux does but with a much cheaper price tag.[email protected] said:No need to get rid of anything. If you have the factory cd changer, all you need to do is slice open the cd changer wire, and in it you will find the left and right audio wires. You can interrupt these with a relay, and connect you external source to it. At the flip of a switch, you go between cd-changer audio, and your external source.
