In the middle of installling my d3, but for some reason the factory antenna doesnt fit in the d3 its way too small, is there some kind of adapter I need? The radio is a pioneer avic d3,

I will have tons of answers for people on the installation later when its complete, but have to get by this first!

 

Well I figured it out myself and my D3 is installed, what a job!! Thanks for the help on the antenna problem[>:]

 

Sorry I just saw this. But yeah you just buy the GM Antenna Adapter. Sorry man.
