I can not use polarized in my 4Runner if I want to see my GPS screen.

Testing for polarization is easy if you have two sets of glasses. Hold one in front of the other and you should be able to see through the lenses, pretty much like it was a single set. Now turn one set to where it is 90 degrees to the other. You should not be able to see through at all
