No overheating issues on my test sample, image quality are a bit basic it seem but by no means poor in my eyes. But i dont think there have been any ajustments to the image quality such as ajustments to chsrpness or contrast.
As far as i can tell the ACC parking mode ( motion & G sensor ) are still not working with the OBD adapter, we testers was told to use the other options for those 2 and time lapse parking mode.
All my findings i have posted in my thread in here

But its not a review i am doing there.
ATM using the OBD adapter to "hard wire" some times the camera turn off, when it should transition from parking mode to normal mode, this happen every 2-3 times if a drive session have a few stops in it.
I wanted to change back to regular power as i dont really need parking mode for the side cameras ( i use the K2S as side cameras now )
But due to the infection in my leg the past month have been pretty tame in regard to getting things done.
But ! i am pretty sure on regular power the K2S do not miss a beat, it dident when i first tested that option too.
Bitrates are not overwhelming, i would like to see them a bit higher, but in my initial testing it captures readable plates as good as the Street guardian cameras in my car.
You have to use one of the parking modes, so motion / g - sensor or time lapse, as i recall you cant combine them.
