Anyone experience this choice when ordering a sunshade for their 2017 Titan? "With Sensor" or "Without Sensor" were my two choices. I tried to use the on-line chat on the site I was looking to buy from, but it appeared the guy I was conferring with had no idea either. So, getting impatient, I ordered "With Sensor". Got it delivered today and there is a huge gap around the mirror, in the exact shape of the shaded part of the windshield behind the rear-view mirror. I understand the shaded part of the windshield acts as a third visor (so to speak) and blocks sun from getting into the cabin, but it is not considered a sensor, or is it? How can something so simple be so messed up? Maybe it's just me. Can anyone chime in on this. When they say "sensor", I'm thinking some sort of physical gadget from the factory around the mirror, not the black-dotted area in the windshield around the mirror.
