So I just got my SG9665GC installed and went for a test run just now. So far it works really great!
It's also a stark reminder that I really need to wash my windows...
My only issue seems to be with glare and reflection of the dashboard. I have my unit installed just to the right of the rear view mirror anchor, about 1.5 inches away (so I have room for my fingers to insert/eject microSD card, and unmount from the unit's anchor). As you can see from the screenshot, the reflection from my dashboard is quite apparent. Any tips on getting rid of the reflection? I've already angled the lens up a little bit, since I don't need so much of my dashboard in the view.
