Does anyone know of an ongoing problem with an E-Z Pass working for a 2006 BMW 750i? Is there a certain location on the windshield I am supposed to place the tag? Everytime I go through a toll the tag is not able to get read, so I was wondering if there is a certain area I should be placing the tag. I have contacted E-Z Pass and they just sent me a new tag which still has the same issue. And the E-Z Pass rep is still not sure how to fix the issue.
