If you need a parking mode, then this firmware will not work for you. (talking about v1.02)
Sorry, I am a bit late to this discussion, but still would like to throw in my 5c worth...
Just to avoid confusion - v1.02 WILL work correctly with parking mode.
And so will the next version v1.03build20190911
However, all subsequent v1.0X builds, starting from v1.03build20190924, will not work correctly with parking mode, but only if you are not using the HK3 kit.
When using HK3, the parking mode will work fine with any version.
Viofo fixed that "parking mode" bug (when not using HK3) in one of the v2.X onwards. From the memory, it was either 2.3 or 2.4.
Anyway, it definitely works fine in 2.5 and 2.6T.
And once again - if you use your A119v3 dashcam with HK3 kit - none of the above is your problem. The dashcam will work properly in parking mode with any firmware, when powered via HK3.
Just a word of warning: all above-written applies to the official VIOFO firmwares only.
It has been observed that some of the vvs49's firmware mods that involve boosting a bitrate, also work incorrectly with parking mode, with or without HK3. Keep that in mind.
Hope someone will find this info helpful.
