Greg, thanks. But Logjam are the guys who told me their GM9-Aux won't work with my radio "because of the limitations of the factory radio itself". That is all they told me. Their Application Guide indicates that the 9-Pin Data Port at the rear of the factory AM/FM/SINGLE CD Headunit (that describes my radio) is used for an OEM Cassette Deck and not compatible. I don't have such a Cassette Deck installed and I'm unaware that any such thing was offered, but I figure they know and I simply don't understand.
I emailed another outfit offering what is probably the same type device hoping they'll know more, hasn't replied.
I'm baffled because this was such a common Pontiac Radio option in the Sunfire, TA, Grand Am, GP, Montana, etc. for several years, I figured somebody would have developed a solution.
Jason, thanks also. I had been to the Instructables site, found numerous examples. But all indicate that you either need a blank tape in the Cassette Player or a Blank CD in the CD Player. That sounds like a nuisance, especially since the converted units being sold don't require that. But more than anything, not being an electronics wiz, I wouldn't know how to mimic in my Pontiac radio what's been done in some other brand. Really need somebody that can tell me exactly what I need to do or at least provide a schematic for my radio to work from. Closest I found was a guy that converted a TA Radio, same Radio as mine except his had the Tape Player instead of the CD Player.
Perhaps the conversions that are being done are more complicated than I imagine.
I figure it is just a matter of having the proper Radio Shack Jack and then knowing where to solder it to the Board. Maybe cut a trace or two. If it is more than that, like requires special electronics be added to the circuit, then it is over my head anyway.
I'll keep searching. Thanks again.
