The App_Tronics Smart NAV ROCKS!!!!!!!!! Raw footage from the track today, note the windowws down on the car and 100+ MPH makes for poor sound quality but you get the picture. Also on the viewer supplied you get G forces and NAV of the track.. That alone os super cool. I cant waite until you can download the file with the speed, g force and other data.. Beyond happy! NO more ugly go pro hanging off my car! Plus all the other features this is a must have. http://www.youtube.com/channel/UCr0cR_9-H7y2rnpsexlBwRw
