For those interested, we put in a $90 Kenwood single DIN head unit. It's awesome. Crutchfield is a bit more spendy than other sellers, but their customer support is top notch. We got the steering wheel interface, the interface to connect to the factory amp and Sirius XM. Around $200 all-in. Installation was cake. My son changed the colors on the Kenwood to match the Pontiac's backlighting. It looks like it came from the factory that way.
