A friend's '17 Premium w/Eyesight was parked next to my '18 Touring this morning and we were comparing some of the features. What we immediately noticed was the difference in the Eyesight (or related features) setup. His has what appears to be a third center-mounted camera (or similar-looking sensor) that's part of the rear-view mirror mounting module. He also has a small black wired module on the inside left upper corner of the windshield that has an antenna-like protrusion on it. Mine has neither of these. What gives?
