Mine uses the cigarette lighter and there are no wires trailing across the dash. The wire goes up behind the glove compartment, tucked in behind the A pillar then tucked under the head lining. All installed in 5 minutes without removing anything. Mine is an Anytek that is 6 years old, battery never really worked for more than a few minutes but camera works fine with the ignition on. Gave up on suction cups and got a little adaptor that attaches to the stem of the rear view mirror.
