I'm trying to figure out the best place to mount my I-PASS transponder on the windshield. My salesperson said that it must be mounted all the way at the very bottom right so that it doesn't interfere with the camera/radar sensor. I'd prefer to place it at the top right, as I find this less distracting for the driver. The manual seems to indicate that any place is fine as long as it isn't in the area indicated by the red circle. Does anyone have any personal experience with this?
