1) Am I supposed to keep loop recording on, as well as Parking Mode?
2) Does loop recording stop when I'm parked, and parking mode "starts"?
3) What is the "normal" setup for this dash cam in terms of what mode and type of recording to use?
With Parking Mode enabled there are three possible submodes: 1) Normal recordings (at the set resolution and fps), 2) Standby mode (not recording), and 3) Time-lapse recordings. Parking mode can be enabled all the time, while driving or parked, hence is autonomous. The camera records in Normal recording mode until it senses no camera/car movement (by G-sensor)
and no motion in the camera field of view (FOV) {Edit: Motion Detection} for 90 seconds. Then it goes to standby mode (not recording). When motion in the FOV is sensed by the camera, it switches to Time-lapse recording. If motion in the field of view ceases for 90 seconds, the camera goes back to Standby. A bump to the camera/car (G-sensor) while in either Standby mode or Time-lapse recording mode will cause the camera to switch back to Normal recording mode. To resume Standby or Time-lapse recording, the Normal-Standby-Timelapse recording cycle must repeat.
To answer your questions:
1) Yes I would recommend that. The Loop Recording setting is applicable to "Normal" recordings with Parking Mode enabled or not, and most folks prefer the three minute setting. Time-lapse recordings also loop but differently. The Time-lapse mode always records two minute duration files, but the actual clock time recorded (end time minus start time) varies dependent on the Time-lapse setting set in the Parking Mode menu selection.

2) No. The camera will continue to record Normal recordings with looping until conditions are met to switch to Standby mode.
3) Parking Mode operates autonomously, i.e., requires no operator intervention to activate when going from driving to parked or back as long as the camera remains powered. Effectively, recording Normal Mode (recording continuously) is also an autonomous option too, but does not save file space on the microSD card. Other modes (motion detection, Time-lapse, and a combination of the latter two) could be used while parked but require the operator to switch the camera modes when going from driving to parked and back.
