-We doubled the technology crammed into our cars.
Keeping your eyes on the road is proving harder to do.
A new device aims to help.
-In half a mile, turn left onto Mason Street.
-The Garmin Head-up Display or HUD projects navigation information onto car windshields in the driver's line of sight.
-It is a technology that you may have seen in like fighter planes in movies and on certain sports cars and
basically what it is, is in remote display for a GPS application that runs on your phone.
-That's worth repeating.
The $150 device is strictly a display.
So, users must buy a separate GPS app from Garmin that a lot at least $50 to your total tab.
A few car makers including BMW and GM offer optional Head-Up Display for dashboard data ranging from speed to cruise control information.
But for now, Garmin is the only after market model available.
To set up the device, there are two options.
-You can either clip a plastic shield on to view the Head-Up Display or you can install the film on the vehicle's windshield.
That's the tricky part of getting that film lined up because it's semi permanent.
-Garmin doesn't sell extra films yet.
So, make your first shot count.
The display offers directional arrows, distance to your next turn, your speed and even lane guidance.
But unlike many GPS devices, there is no detailed map.
The good news is the information is easy on the eyes.
It's got a light censor on the back of it, so it's automatically monitoring the ambient light around you.
So, during the day time, it really brightens up so that you can see it in direct sunlight, and at night time it dims so that's night dazzling you while you drive and you keep a little bit of your night vision that way.
-It's another way to navigate around but it may not appeal to everyone.
-Every three months it seems we get a new form of GPS, a new device supposedly risk-free.
Every driver needs to take that decision and make a personal choice because
different devices are gonna be easier for different people.
You need to choose the device that's gonna post less distraction for you.
-Another tip, no matter what kind of map you use, be sure to plan your route before you start your car, in other words, safety first.
