First of all, the GT300W picture quality is Superb.
I drive daily trough tunnels and the white balance (even in the poorly lit tunnels) is unsurpassed.
This mini tutorial will show you how to mount the polarizer filter and change the suction cup bracket.
GARMIN MINI BALL MOUNT
The dashcam comes with a humongous suction-cup mount.
I live in a climate where 43C temperatures and 90% humidity are the norm.
Thus suction cups do not seem to hold.
Secondly, the standard suction cup is almost bigger than the camera!
I purchased a mini, permanently self-sticking Garmin mount.
The ball opening is slightly smaller but it is such a tight fit that you do not need the screw to secure the ball.
These mounts sell for approx. $4 on eBay
POLARIZER FILTER MOD
I have a very light dashboard which causes quite some reflection.
A Polarizer filter would take care of this issue but there is no way to mount it on the dascam.
The lens diameter (outer diameter of the lens housing) is approx. 29mm
Thus in theory we could try to mount a 29mm polarizer filter, BUT...
The lens has an extreme wide angle, what this means is that it would show the edges of the filter, also know as vignetting.
What do we need:
a 43mm Polarizing filer (approx, $19 for a good one)
a 27mm to 43mm adapter ring (less than $4)
2mm wide double sided tape (3M or similar brand) (this type of tape is used to glue phone LCD's)
Fixate the ring with the double sided tape to the lens
Voila DONE
Notes:
The are good and bad Polarizing filters (don't buy junk)
A Polarizing filter is made out of 2 lenses, the outer lens rotates.
Before mounting the filter, sit in your car and rotate the filter until the glare is gone.
Mark the position.
Mount (screw) the filter on the dash cam and make sure the outer ring of the polarizer filter is at the same position as tested above. (you might need some fine tuning)
Depending on the quality of the polarizing filter, the picture might be slightly darker.
In this case, you can adjust the settings on the dashcam.
ENJOY
