Hi, I was wondering if anyone had already tapped 12v power out of the rear view mirror assembly. I have the drivers assist package (lanekeeping) and rain sensing wipers, if that matters. I need to install a dashcam and prefer to pull the 12v power from there rather than a horrible cable routing all the way around the dash. I know these aren't speed demons but I figure someone might have installed a hardwired radar detector or other device...
