'99 Sunfire with factory AM/FM/Single CD & 7 Band Equalizer. Used in many Pontiac models mid '90s until at least '02 in some.

My son wants to add an Aux Jack for Ipod (has used a transmitter, but would prefer a jack). Searched all around, at least two guys have sold same radio they convert to add a jack. They get pretty good money for them but I'm trying to work with my existing unit to save $$$.

Found an adapter (GM9-AUX) that seemed perfect but seller says won't work with my radio, even though I believe it has a 9 pin connector at the back. Supposedly doesn't work with '95-'99 Radio with single play CD, something about the 9 pin jack used to control an external Cassette slave unit. Over my head. If somebody knows of one that will work with my radio, that would be great.

The guys adding the jacks to this same unit say it works without having a CD playing. In fact, I was told the CD is not on when the Ipod is in use. Of course, they don't want to tell me how to do it myself.

The proper way seems to wire the jack into the preamp somehow. When the Ipod is plugged in, it overrides the radio. No toggle switches, simple plug and play. All functions work normally, if a CD is inserted, it overrides the radio or if the Ipod is plugged in, will override that too.

I've searched all over but haven't found any instructions for doing this on a factory radio. I found an LS1 site, guys adding a jack to the connector between the radio and CD Player, but it requires the CD to play a blank CD to make it work. Gotta be a better way. Does anybody know how to wire a jack into this radio to work without needing a CD playing?
