In case anyone is interested in hard wiring a radar detector it's really easy on this car. You dont even need to remove the a pillar the whole way.
Mount your radar detector next to the mirror.
Push the cable in the headliner to the a pillar.
Pull down the weather stripping.
Pull the a pillar to remove the first stage.
Run the wire down the a pillar and push it to the foot well near the bottom.
Run the positive to fuse 41. This turns on/off with the ignition.
Use one of the bolts in the foot well for the ground.
10 minutes tops. I put the positive right on the leg of the fuse, but you could use something like this too
