In car HUD from Garmin.

_68605873_garmin_hud_1-1Sat-nav firm Garmin has made a heads up display (HUD) for car windscreens. The portable HUD works with a smartphone and Garmin sat-nav to place turn by turn directions up on the windscreen.

It can project directional arrows, distances, current speed and speed limits on the windscreen. Information is provided via the HUD’s attached reflector lens or a plastic film stuck to the windscreen.

The navigation system can also provide voice prompts via a smartphone’s speaker or a car stereo that works with the Bluetooth short range radio technology. The app associated with the sat-nav system is available for iPhones, Android phones and Windows Phone 8 handsets.

Brightness levels of the display are adjusted automatically so that the display can be read easily both in the day and in the night. Tim Edwards, a principal engineer in the future transport technology division said ;

“Car makers are starting to do this themselves but their challenge has always been development lifecycles, Your smartphone changes almost daily but there’s a limit to how fast a car can be updated.”

HUD’s are starting to become a standard feature now in mid range vehicles, and are no longer confined to top level makes and models. However the gadgets are often built into the car and cannot be updated or modified.

HUDs that project information on to windscreens can cut down on driver distraction as people spend less time looking down at instruments and more with their eyes on the road, Tim added.

Garmin said its HUD would cost about $130 (£86) when it went on sale in late summer. Regional maps for the associated Garmin app will cost about $30 (£20) each.
