I am needing to figure out how to play my mp3 player through my oem head unit in a 2000 sel with the ecc package. I have seen the post about wiring it up as the tape input but I want to utilize my cd changer (i have no changer) wiring in the trunk. Is this possible. Your assistance is greatly appreciated... oh yeah... and i know there is an adapter for this but i recently loss my job and funds are TIGHT so i am trying to do this as cheap as possible. I currently use a cassette adapter but have a feeling this would significantly improve the audio quality.
