Many modern cars come with some form of easily readable heads-up displays, but they often don't offer much information beyond how fast you're going, how much gas is left, and perhaps your current fuel consumption. A third-party, add-on HUD for your car can provide you with all kinds of other essential information, all while letting you keep your eyes on the road, so you don't need to glance down to check your gauges.
This HUD from ACECAR displays more than just speed and mileage onto your windshield. In addition to the speed of your vehicle, get readouts for water temperature, engine speed, distance, and battery voltage, as well as alarms and reminders for high temperatures, and excessive speeds. The best part though is that it supports both GPS and OBDII modes, making it one of the most compatible around.
Plug & play
LeaningTech's heads up display is easy to set up and use, plugging into your car's cigarette lighter for power. It connects to a GPS satellite to deliver real-time data on your speed and easily switches between Miles and Kilometers Per Hour.
Another HUD that plugs into your cigarette lighter, ITEQ's unit keeps you headed in the right direction, displaying GPS-aided speed, altitude, and current direction.
Everything you need to know
Plugging into your car's OBDII port, Arestech's A8 HUD shows driving speed, engine speed, water temperature, battery voltage, current, and average fuel consumption, shift reminders, and so much more.
Small, light, powerful
Keep an eye on all of your car's vital information with this compact HUD unit, with gauges for speed, RPM, voltage, and more. Ambient light sensor automatically adjusts the display depending on the light outside of the car, so your eyes don't get strained at night. Plugs into the OBDII port.
Roll your own
There's an app for just about everything, even some that turn your phone into a heads up display. When combined with Armor All's Heads Up Display mount, you simply launch the app of your choice, set your phone down, and adjust the reflective surface to get started.

These heads-up displays are a great way to keep an eye on your car's essentials stats, from speed to water temperature, without taking your eyes off the road. The ACECAR Heads Up Display offers all of the information I'd want without overloading me, projecting everything on to the windshield and reading that information directly from the car's OBDII port or via GPS.
If you want something a little more compact, WonVon's X5/X6 Car Windshield HUD also plugs into the OBDII port, and while it's not as easily readable as the ACECAR, it still provides a lot of information. If you're looking for something that works with an app and your phone, check out the Armor All Heads Up Display.
