Highly unlikely I was in your boat to as I like to find the cheapest way of doing... well just about everything. BUT I broke down and bought it from amazon I did buy it from ebay but after two weeks I didn't receive it and got a refund so don't buy them from seller autoware302on ebay... scammers... GM12-Auxv2 PIE is the model you need well for my 06 GP at least. ANYWAYS its worth it ... simple clean install and you keep steering wheel functionality worth it in my opinion. I modded mine... drilled a whole in my cubby under the climate control and fit a 3.5mm aux cable through it so now when I need it i just pull it out and when I dont i just put it back in.
