Parking mode in the dark

[xtapac]

Recently discovered a problem with my A129 Duo, at the daylight parking mode (2-wire) works as expected, but at the night - sometime it never switch to the parking mode, sometime it does but constantly recording 5fps thinking that there is motion in the frame.
I think the problem is a noise on the video, but why did everything work normally before? Maybe the sensor is broken, because Rear camera didn't have such noise.
Did not find such problems on the forum, maybe someone faced this before?

I have tried to downgrade firmware to 1.42 and to 1.3, and result: 1.42 quite the same issues as 1.5, but 1.3 works as expected.
I think I understand the reason, at the night car was parked at underground parking, and there GPS is unavailable, but sometimes a small movement of 1-2km/h appears.
So maybe someone knows, does 1.42 version relies on GPS while entering/exiting 2-wire parking mode?

How to enter and exit parking mode:

1. With 2 wires hardwire kit: Enter the parking mode after 90s no motion, exit the parking mode while there is a G-sensor detection or average GPS speed is >8KM/H.
2. With 3 wires ACC hardwire kit: Enter and Exit by ACC signal detection.

Applies to V1.42 and V1.5. Does V1.3 have parking mode?
