Review on PAC RP3-GM12 Radio Upgrade Adapter for GM Vehicles without On-Star by Joshua Talbot

Does NOT fit my 2006 Chevy Silverado. It's hard to explain, but the (grey) connector in my truck has two offset notches on the bottom. These notches did not match the notches on the (blue) connector of this adapter. (See attached photos.) I ended up buying a new wiring harness and having it professionally installed. Let's see what happens when I try to send it back.
