I recently bought an Edge, live in Arizona, and found the glare on the windshield to be a dangerous situation.
My color is stone.
I did get a Dash cover but it did not make a hugh difference.
While looking at sunglasses I remembered reading a comment on this forum that "polarized glasses" worked.
Since I wasn't ready to trade the Edge and Ford gave a ridiculous response to my concern I bought the polarized glasses.
The effect is TREMENDOUS!
Ford should provide a pair of these with every Edge they deliver.
The glare becomes a non issue.
If you are experiencing a glare problem give this solution a try.
