Garmin dash cam and polarized filter test. Model 57 vs Mini 2

I wanted to test how polarized filter will effect to the reflections in the window. Will the filter add more noise, is it going to effect much to the video quality. At the same time I can see the difference between 1440p and 1080p resolutions. Is there a big difference.
This is not a very scientific test, just a test in real life situations.
I'm surprised, how well Mini 2 model will do in a good day light conditions, Model 57 is better in a low light situations. There is also a big difference, what comes to audio quality. I didn't notice much difference in noise, between filter or no filter.
I didn't do any post processing to the footage, no color corrections or anything like that. GPS information I moved to the middle of the screen, originally it is in the lower left corner.
