Has anyone used this
http://www.beatsonicusa.com/other-ac...ies/cs3ep.html and installed both a front and a rear camera? It looks like you can have it be automatic for parking or just use the switch for a preprogrammed amount of time. It seems very helpful for those that don't want to chew up their lips or splitters with going too far by accident or not seeing something you didn't know was there.
