I'm very happy with my PDC... I got the aero body kit, and a little scratch can be very visable as compare to the origianl black hard plastic bumper... the PDC helps a lot.

Once engage in Reverse, the PDC is switched on. It will be switched off automaticlly when you switch off the engine, or drive away. Or, you can switch off manually with the switch in front of the shift stick (no steering wheel button for it, as mentioned above.

Hope this helps.
