Head-Up Display Speedometer, puts your speed right on your windshield.

At 65 mph, looking down for one second to check the speedometer means driving blind for 95 feet. Many accidents start during the time a driver glances down and fails to see sudden traffic changes ahead. Now, drive safely by never looking down to check speed again with this Head-Up Display Speedometer. You may also set over-speed warning with the touch of a button. When the preset speed limit is exceeded, a visual indicator lights up and an optional alarm beeps (for up to 15 seconds) to remind you of the speed limit.

 This "heads-up display" is a bit like those in pricier rides — like F-16s (and the occasional Cadillac). It is a dash-top device has a small but bright monochrome display that is simply reflected in a special transparent sticker you put on the windshield.

Why get this, you ask? Some people will prefer the minimal, single-color display over the occasionally gaudy and distracting LCD. A bit of cool blue text, an arrow or two, and some voice directions are more their style. And automatically adjusting brightness means it'll be visible in broad daylight but won't blind you in darkness.

Get your device mounted exactly where you want it before you put in the reflective window film. You will want to mount it, then drive to test it at speeds in the double digits. You need to see the double digits so that you know that you have the angle just right. Mount, adjust, mount, adjust, then when you think you have it perfect you should mark the location with a pencil. Remove the tape. Clean everything with rubbing alcohol. Then remount. Then test again.

Putting the film on the window is tricky. Like tinting windows, or applying a screen protector to a cell phone. Wash your hands first. The oil on your fingers will cause you problems. Then apply a little soapy water to the window and the back side of the film. Place it where you think it goes, but don't brush the bubble out yet. Drive a little while the water is still there to test the location. When you think you have it, then you can work the bubbles out.

The HUD uses GPS to determine the true speed of the vehicle. The GPS gives a more accurate reading than the speedometer (which reads slightly low on my new car). All the functionality of the factory installed unit at a fraction of the cost! Very helpful when driving through town. Once you get used to having it you will miss it whenever you drive any other car.
