There has to be a 12V+ reverse wire somewhere up front.
It's honestly like less than a ten minute job.
Just tap into the reverse light on the passenger side, route the wire behind the interior trunk covering, pull out the back seat and route the wire under it, push it under the trim around the doors, and route to the stereo.
