I recently upgraded from a 2014 S85 (pre-AP) to 2016 P90D (AP2). I had previously hardwired my Passport Max into the rearview mirror and would like to do something similar again. I know there have been a zillion similar posts but they are all about dash cams or older videos. Can anyone guide me to a quick video or pics or tutorial to do this? I don't want to screw this up. Thanks!
