When my new truck arrives (2008 GMC SLE 2 Ext Cab Dually LMM) I want to replace the factory Audio system with the Avic-D3. What do I need to do to remove the audio system, special toold etc.?? How do the dash pieces come off?

the dash just has pop clips that hold it on...its harder to get back on than it is to take off. I would assume that the new stereo would be mostly plug and play.
