Recently bought an 05 ss/sc and I have a pioneer app radio 3 that I want to install. I've read a few different threads saying if I use a double din radio the driver information center cannot be used? In my 05 the display for the dic is under the tach and the two buttons to operate it are next to the steering wheel. I have the pioneer system and Xm but NOT onstar. Is it possible to install a double din and keep the dic? I won't miss the Xm it's not going to be used anyway and don't mind spending a decent amount on a wiring harness but have no idea what to get.
