Stereo & Electronics - 12 Disc CD Changer Simple Question

I know this is a stupid question, and I read the FAQ and maybe I over looked it. I loaded up my factory 12 disc CD changer and I can not figure out how to play the CD's in the changer. I can play the CD in the head unit and if I eject it I cant figure out how to switch it to the CDs in the changer? Thanks

"AUX" button, if it works. My trunk changer's been dead
for at least a year now, though, and it doesn't anymore.

Sounds like that is my issue

Also, make sure you loaded the discs "upside down". The factory changer expects the discs to be label side down in the trays.

Pressing preset 4 would cycle the cd's in my cd changer unit

Not trying to hyjack. Does my car have the wiring there for the CD changer? What side would it be on in a convertible?

All 98-02 Monsoon equipped f-bodies came with the wiring harness for the external changer pre-installed. You should find it in the left side of your trunk with the end wrapped in foam and taped to another wiring harness.
