Im not getting any of the concerns your finding? .. Maybe try mounting the unit on a different part of your windshield?

It would be fine if the unit was able to be fitted either left or right side of the vehicle (OK on the right, but gesture sensor is inaccessible when on left). My vehicle has embeded reflective screening in the glass around the rear view mirror position that cannot have even labels placed over it, so I am limited to top of w/screen left or right of mirror!
The reflections seem to be due to the slope of the screen, the steeper slope the further the camera lens is away from the screen surface and the worse the reflection problem becomes. When the camera is positioned on the left (passenger side) the reulting video does not fully show oncoming traffic.
My best option seems to be some form of lens shade on the bottom side of the camera, failing that I will hsve to return it "as not fit for purpose".

Im yet to figure this out too .. When I park it says parking mode activated and then 30 seconds later it says leaving parking mode so not quite sure to be 100% honest ..
