Like most things in newer cars, the radio is integrated.

Get the correct harness. You're talking $20 tops. Splice that into your new radio's harness. Soldering is best, but butt connectors are OK.

You're gonna need an antenna adapter anyway. GM has for years used a mini Motorola antenna plug. Most aftermarket units use a full sized Motorola connector.
