Speaking of CPL my experience has nothing to do with adjustments as I have found none were needed in my case. However, after installing dashcam and several test drives my video(s) were grainy/fuzzy then realized a new firmware (1.8) update was available so completed the upgrade with same results. After verifying settings decided to remove CPL for cleaning and to make certain I had removed protective plastic lens cover from dashcam. On close inspection the issue was found, although I had removed the outer protective plastic covering from CPL and dashcam it was then I discovered there was also a protective lens cover on the inside of the CPL. Although I felt like a fool
in not noticing in initial setup it does go to show the level of detail from Street Guardian even in packaging. Enjoying great video experience now..
