Navigation remains the primary purpose of the HUD, so it’s a permanent fixture on the display, with notifications appearing in conjunction with the navigation elements, rather than replacing it entirely. It can also connect to the car’s computer, letting you monitor performance and diagnostics right from the projected display.
To respond to notifications, you can either use gestures (it supports left and right swipes) or voice commands. The latter mirrors some of the features available in Google Voice and Siri, so you can compose messages, call contacts, and control music playback by simply speaking while you continue to operate the vehicle.
A private crowdfunding campaign is currently running for Navdy. Pledges to reserve a unit starts at $299.
