1) The mounts are included. 2) Parking mode is when the camera will come on and start recording automatically, even when the vehicle is off. This way, if you're in a store and someone bumps into your vehicle it will record the incident. 3) You could choose to mount the rear camera in the front for cabin recording, but there is so much cable length that it is meant to go in the rear windshield to record a rear-end accident. The camera screen overlays the rear camera onto the front camera, however, in the recordings, they will be two separate files.
