If you want your DIC date to work use Scosche GM06B and keep your old radio in the trunk. Other options are the AXXESS GMOS-01 for the wiring harness with the AXXESSASWC-1 for the steering wheel control. Another steering wheel control option is the PAC SWI-RC. I didn't really like my PAC steering wheel control box, so I would stick with Axxess stuff. Also the Axxess AXOTG1AN makes programming the ASWC-1 a little easier with an app thru your phone. Your actual radio (like FM 106.3 or whatever stations) stations will go to crap unless you buy a Blaupunkt brand. At least that's what I was told by a professional installer when I asked why my Kenwood wouldn't get very good stations. I didn't really care since I was using Pandora anyway.
