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
