A:AnswerYou have to purchase the Dashcam AND back up cam installation. I believe I paid $180 for it.
Make sure it includes back up cam installation as well as the dash cam
A:AnswerYou can try that. But if that extra $20 is for a part or additional service that is required for the install, you may end up paying for it anyway. I personally would pay the extra money so the tech doesn't feel the need to cut corners or cheap out on the install. You definitely get what u pay for.
