I used it once for shts and giggles on my first oil change. Go to the PDR screen, set it for Valet mode, put in a password...yada yada yada... And it turns on when they start the car. Then when you get the car back you need the password to get out of valet mode off... Then you have to reset your own oil life as they can't access any of those functions when it's set to valet..Oh yeah... Valet mode does not record sound either to protect other peoples privacy... LOL.... Likely will never use it again as have no intention of allowing an actual valet to drive my car.
