I would like to put a transponder for tolls on my 2010 Honda Civic.
This car has a pattern of black dots on the upper portion of the front windshield behind the rare view mirror.
I Googled for a few minutes, other people have asked, but the people responding were unsure of the purpose of these black dots.
Are they simply to cut down on glare?
Is it non-damaging to the car to mount the transponder on these dots?
Anyone know for sure what the purpose is for these patterns of dots?
