We've become so dependent on GPS that a three-minute drive often means frequent glances at an in-car navigation companion. But taking your eyes off the road can be very dangerous, even if it's only for a moment. If you're fortunate enough to have one, a head-up display will let you get to your destination efficiently and safely, and Garmin's got a new aftermarket solution to keep you cruising on the cheap. The company's new HUD projects bright directions onto a transparent film mounted on your windshield, serving up guidance within your regular line of sight. The simple interface displays your current speed and the speed limit, turn arrows, the distance until your next turn and an ETA. The Garmin HUD is compatible with Bluetooth-equipped smartphones running Garmin StreetPilot and Navigon apps. It's expected in stores this summer with a MSRP of $129.99.
