I've got a 2008 G6 base, fully loaded. It has 3.5 V6, remote start & Onstar. I really don't like the factory GM radio & heater controls. Can I install the 2009/2010 G6 XSM radio & heater controls in my car? Would I have to get the 2010 gauge cluster also? I don't wanna loose my info. center. Any help would be appreciated.
