mounted both of ours above the rear view mirror on the windshield. It's up high were it needs to be in the center of the truck, but it's not straight up and down. So it may be close to accurate, but not perfect.
I couldn't find a spot that was straight up and down without using a bracket.
Although the visor would work, somtimes you are in a spot were you can't have the visor hanging down in front of your view to see a spotter.
FWIW..........
