I posted this in a regional section of the board (Sunpass Mini and Gate Openers on Model X) but maybe others have some input as well. In my previous cars and SUVs owner manuals usually described in details where to mount transmitters and other equipment (radar detectors, gate openers, etc.) that needed to communicate through a shielded windshield. Usually there were 2 or 3 unshielded area (around the rearview mirror, and lower corners of the windshield). Here is a copy of my previous Mercedes-Benz manual: 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 optimum placement for 2 items - Sunpass Mini and a gated community access transponder? Has anyone tried mounting these transmitting devices into the falcon doors "roof" glass?
