In my previous cars and SUVs owner manuals usually described in detail where to position transmitters and other equipment (radar detectors, etc.) needed communication through a shielded windshield. Ususally there were 2 or 3 unshielded area (around the rearview mirror, and lower corners of the windshield): Nothing in owner's manual of the Model X. Does anyone knows if Model X has unshielded areas on the windshield? I need to find a place for 2 items - Sunpass Mini and Gated community access transponder. Has anyone tried mounting these transmitting devices into the falcon doors?
