Finally, it looks like we don't need to buy crazy expensive cars to get technology showing turn-by-turn directions right on the windshield. A new device and app turn a smartphone into a heads-up display.
8 Techs Make Cars Smarter Than Drivers
The technology company Garmin recently developed a heads-up display device for about $130 that works with a mobile app and Bluetooth-enabled smartphone to project navigation info onto your windshield. According to the company, the projection can either go onto a transparent windshield film or an attached reflector lens. The display can show the distance to the next turn, speed info, traffic alerts and an estimated time of arrival.
This HUD automatically adjusts the projection's brightness level so it appears clearly no matter what the time of day or night. That's probably going to be much safer than relying on a propped-up smartphone or GPS device nestled in the car. As AllThingsD's Bonnie Cha pointed out, this heads-up display approach could be a new direction for companies that currently make those standalone GPS devices.
