So i was a little bored yesterday evening, so to pass time i found the little CPL filter supplied with the 0806.
First i was making a little bracket of some plastic tube i planned on gluing on the SG9665GC, but that do not work as the lens of the dashcam is so close to the windscreen.
So i enden up with taking the glass out of the 0806 CPL filter, and that alone did work but have to be used with the tall of the 2 mount brackets supplied with the SG9665GC, the reason for this is the glass from the CPL filter is "large" in diameter so on the low bracket its a extremely tight fit.
For testing i just used 2 sided tape to glue the CPL filter onto the SG9665GC, but doing that i have no means of ajusting the CPL filter by turning witch seem to be the norm.
So in desperation i held up the CPL and looked thru it at my LCD tv, and then turnes the CPL untill it got dark, i then assumed this was the "this side up" mark and i glued it onto the dashcam that way.
But today i found out that assumption is the mother of all farwkups cuz in my footage there is still reflections in my windscreen
So for my drive tomorrow to aid my friend i have planned to pry the filter off the dashcam while in place and then try to rotate it in front of the lens to find the sweet spot, and then press it back on the 2 sided tape.
I can not do more with this at the moment as my cam is still only test mounted in my car, but when i get it in its permanent place i will use the tall mounting bracket and make sure i have enuff clerance between dashcam and windscreen to proceed with my CPL experiments.
So to sum it all up.
It can be done, but you have to use the tall mounting bracked, and maybe even make that even taller to make room for CPL filter.
The 0806 CPL filter is not tall, around 4 mm i think, but as is there is no room for it at least not using the low mounting bracket i use ATM.
