Great questions! I will get some more pictures perhaps next week and update the album and post. That would be a good opportunity to replace the included Ethernet cable with a longer one.
Removal of the center console panel is easy:
1. Start with the cubby under the stereo head unit. Gently lift the front of the rubber mat just a little, and you will notice there is a plastic lip there under the rubber mat.
2. Use a thin trim removal pry tool to release/pop the cubby tray upward.
3. Now you can use your hands to grab the front of the center console plastic panel, and pull upward gently to release/pop up.
4. Now use your pry tool at the other end of the panel, at the rear of the car, under the rear-most straight edge of the chrome accent, rearward of the curve that is to the right of the parking brake lever.
5. Once you release/pop up this part of the panel, the rest will pop out easily by just using your hands along the edges working your way forward from the rear, toward the cubby tray.
6. Unplug the wiring harness for the parking brake lever by depressing the tab and then pulling the harness downward; it's a little tight.
7. Now you can pull the whole panel out easily by just moving it forward into the cubby tray area a little until the gear selection handle fits through the opening while lifting the panel away. You can remove this while the gear selection handle is still in the Park position, no problem.
As you'll read in my photo album, and I'll add pictures of this later, the location where I installed the knob is the only place on the entire panel where it will work. There are no other places where both the underside connectors, and the obstructions from below, will allow the length of the button controller to fit. You don't even get a 1/2" of variance in either direction from where I installed it. So be sure to double check and triple check its placement before you start drilling the holes!!
Hope this helps!
