What harness is needed 08 non Bose?
at the moment I have Aftermarket sub and amp using the add-gm24. I want to update the HU from stock and keep my aftermarket sub and amp. What harness is needed? Can I use the ADD-GM24 or requires a different harness? I've been searching for hours but my internet is CRAWLING!

You can leave the Add-GM24 in place and just add a C2R-GM24 or RP3-GM11 in front of it for the new radio, or either of those two adapters on their own. Neither will retain onstar or steering wheel controls. If you have SWC you can add the HU specific interface or just get an RP5-GM11 on its own.
If you call Dennis at DoubleDmods.com he can set you up with the best one for your situation.

If your new HU has a separate RCA sub output, use it and ditch the Add-GM24. If not, leave the speaker outputs on full-pass (HPF and LPF off), connect the four RCA outputs to the new interface adapter, and leave the Add-GM24 in place.
