My cable was about 6-12" too short for my liking, and that's in a Nissan Altima sedan, routed around the windshield, down to the carpet along the door, along the bottom of the floor, up the edge of the rear seat, back to the rear windshield, up the rear windshield's edge and up around to the top middle of the windshield.
Would be nice to know where to order longer cables if I change cars or for other family members, I searched for a longer cable when I got the dashcam, but couldn't find one, this male to male is a non-standard type, so it's not carried anywhere other than supplied in the dashcam box.
