Has anyone successfully tapped into the 12V hot lead in the rear view mirror? If so how difficult was it to get to? I'd like to power up a portable GPS unit from there without having to have a power cord lying on the dash.

I found a 12v accessory line up there. I used it to power my dashcam.

Unfortunately, I didn't document it or take photos. But in short, there's a wiring bundle that traverses the roofline from the driver side to the mirror. I probed the wires in there with a multimeter to find one that was only hot when the car was in on/acc mode.
