Guys, as for mounting the actual radio, I had mine mounted on the panel that sits below the steering wheel. It sat right in front of my left knee and I always hit it getting in and out of the truck. So about a week ago I moved it right into the dash. I have an 06 with the REQ (I believe), so I don't have nab. All you have to do is remove the bezel covering the factory radio, cut out a little bit in the center and vuala.....you have a CB mounted right in your dash!
I ran the wires right by the ignition, down into the fuse box area. And if you make good cuts, you don't even need to secure the CB in place, the pressure of the bezel is seriously plenty to keep it snug and in place. I wheeled a little today with it in there and it didn't move an inch!
