This is the first major mod to the car. I put the Garmin 2720 in the ashtray area. It is a rather nice fit, I was surprised that it also gits excellent reception down there. I also hardwired my Escort 8500 to the car and placed half of the plug (I cut it in half) for it right above the GPS unit. If I need to I can still get to the ashtray area. By the way, the shift boot and knob are all one piece....it just pops off. The ashtray area is held in with two torque screws and then just lifts out.
