Radar Install
First step was to remove the visor, which involved removing a bolt and disconnecting the wiring harness that powers the homelink* and vanity mirror light sensor (Time: 2 minutes)
Next, had to remove the grab handle, which meant flipping down the bolt covers on either side (used a 90 degree flathead, did the trick well) and removing the bolts. (Time: 2 minutes) There's a bolt behind the "Airbag" label that also has to be removed (No Picture, Time: 1 minutes)

Next, had to use my hands (screwdriver threatened to break things) to pry off the a-pillar from its clips. (Time: With some aggravation, 5 minutes) Take off the fuse panel cover. This is easy.
Next, I dropped the knee bolster and removed it. To do so, there are three bolts to be removed: 1 next to the fuse panel, 2 at the bottom of the bolster. Then you lift it back and out, and disconnect anything you need to (i.e. OBD connector, light connection) to remove the bolster altogether. This entire portion is completely unnecessary for the radar installation, I just thought it'd be cool to poke around down there, and it turns out its real easy to install/uninstall. It comes in handy for hiding away the V1's direct wire unit too.
I used a piggyback to connect the power for the detector, and grounded it to a bolt that holds the fuse panel in place. The fuse I used was number 31, a 15A fuse for the reverse lights and one or two other things. Its ignition switched, so the radar detector turns off when the car turns off.

Run the wire for the radar through the top of the headliner, down the a-pillar (I zip-tied it to the airbag supply wire) and into the area behind the fuse panel. Secure the V1 adapter well. Replace everything, and that's it. The a-pillar was very difficult to replace, and I actually broke off the bottom retaining clip in the process (although it doesn't seem to matter much). Everything else is cake.
