I just bought a SunPass from a store. I know from seeing them around town that they go on the windshield. I was wondering if anyone has used one on their wing and found a better place to put it that it will still pick up. I just dont want to mount this thing on the windshield. I know we used to have the "EPass" and they would mount them under the front end of a car and they would pick up fine. Thanks for any help.
