Switched power line

[DJLVA]

I'M hooking up the Nav-DVD kit and was wondering if there is a 12 V power line close to the Nav dvd? I would normally assume that there was a red-black line going to the LR DVD, but was wondering if there is another source to hook onto without tapping into the dvd harness.
Thanks

Center console cigarette lighter pops out and works for power.

Cool Kit.
