Want an iPod interface in my car

[BigBadjohn]

I have an 02 GTP 40th anniversary sedan. I recently bought a new USA spec pa11-gm45 for dirt cheap on eBay
I installed it today but it didn't work. I read the manual and it said I need a source/aux button in my radio to make it work. All I can see close to that is cd/play. Am I doing something wrong or is my radio not compatible
it's a delco theftlock without the full equalizer and it has what looks like a slave harness plugged into the back
thanks

It needs to have a tape player in it, at least, that's how all the ones I've seen work.

I think I have a Pontiac slave tape deck in the garage. Although I don't want to have it
inside the car

I looked up the model you said and it mentioned something about having CD Changer compatibility.

 

[BigBadjohn]

Where does the cd changer go?

 

[SeanGTP]

Dunno, but did you have one? I believe the Bose premium package may have, so that could be your problem.

Not that I know. There's a black plastic box on the left of my trunk but I think that's for onstar
