The dials on your car’s dashboard are essential – they let you know how fast you’re going, how hot the engine is, and whether you have any mechanical problems to worry about. However, every time you look down at these instruments, you need to take your eyes off the road. At highway speeds, you can travel a surprisingly long way without actually looking where you’re going.
Luckily, there’s a convenient solution: head up displays. Sometimes abbreviated to ‘HUD display’, this nifty piece of kit might look like something out of science fiction, but you can actually install one in practically any vehicle. They work by projecting vital information onto the inside of your windshield. Everything from speed to GPS interfaces can be projected this way, and you can install your own for less than you’d think. To help you find the best head up displays on the market right now, we’ve compiled this handy buying guide. Below we run through our 10 favorite options, before answering some common questions about how to get the most out of your new display.
The Best Head Up Display For Cars
Kicking off our list is Arpenkin, with its universal HUD. The device projects vital trip data—from vehicle speed to fuel consumption and mileage. The display adjusts its brightness automatically, so you can easily see it come rain or shine. It’s also designed to prevent any glare from forming on your windshield, reducing the risk of eye strain and fatigue. Arpenkin’s device is compatible with all OBD2 equipped cars, making it incredibly versatile, too.
Handy alarms will let you know if you exceed the speed limit, or the voltage in the battery drops, helping you to stay safe on the road. It automatically shuts off whenever you switch off your car’s engine, too, preserving the battery and giving you one less thing to worry about. Included with this HUD is everything you need to get it up and running—a cable, manual, anti-slip mounting pad, and a special reflecting film for your windshield.

Best Head Up Display For Cars Buying Guide
These 10 head up displays are the best of the bunch, and we’re confident you’ll find the perfect fit for you among them. To help you work out which display is best for your car, check out our handy buying guide below. We’ve also taken the time to answer some common questions about this handy piece of kit.
Features to Look for in a Head Up Display
When it comes to choosing a head up display for your vehicle, there are a few key features to consider:
An HUD is no good if you can’t read the display. Look out for a bright display, which can be adjusted (whether automatically or manually) to be visible in various light conditions. If in doubt, you can gauge the display quality by looking at photos from other users.
Some HUDs can be connected to your smartphone via Bluetooth. This allows you to see your navigation apps alongside other trip information. Many HUDs with this connectivity double up as a car phone, too. If you travel a lot for work and need to take calls on the go, this could be a great feature for you. Whichever device you choose, be sure it’s compatible with your vehicle - some are universal, and simply plug into the cigarette lighter, while others must be wired into a specific OBD system.
Which HUD you select will also depend upon what data you want to see displayed. Some devices connect to your car’s OBD system, allowing them to display everything from fuel consumption to diagnostic codes, while others stick to simple information like speed. Simpler displays are not necessarily inferior, as they’re generally less cluttered, so easier to read.
Benefits of Using HUD for Cars
Installing a head up display in your car comes with a number of benefits:
- Using an HUD means you don’t need to take your eyes off the road to check your speed
- Using an HUD can give you access to trip data you may not otherwise be able to see
- Installing an HUD is generally simple
- Some HUDs can be connected to your smartphone, allowing you better access to your navigation app of choice
- HUDs are available to suit all budgets
- Using an HUD can help prevent speeding and fatigue
How to Install a Head Up Display For Cars
How you install your HUD will depend upon the manufacturer, and you should always follow their instructions carefully.
HUDs are generally installed using one of these two methods:
- Cigarette Lighter
Universal HUDs are simply plugged into your car’s cigarette lighter. They gather data about your trip via GPS, and don’t depend on the car’s internal electronics. These are the easiest to install - simply plug them in, and mount them on the dashboard.
Other HUDs are installed by plugging them into your car’s onboard computer. This allows them access to any data fed into the system. OBD connectors are located in different areas on different vehicles, but you will often find them under the steering wheel. Consult your car’s manual if you’re struggling to find the OBD connector. Once you’ve tracked down the port, it’s a fairly simple matter of making a few connections, and mounting the device itself on your dashboard.
Different Types of Head Up Displays
There are three main types of head up displays in the car world:
- Built-in HUD
Some high-end modern cars have HUD systems already built in. They’re pretty much invisible to the driver, but project information onto the windshield at eye level, through a series of mirrors.
- On-Board HUD
The displays on our list all fall into this category: they’re after-market devices mounted on your dashboard, and project information onto either your windshield, or their own glass display panel. Many can be connected to your phone via Bluetooth, allowing you to view your navigation app, or take calls hands-free.
- Smartphone Apps
If you want to give HUDs a go before making a real investment, you could try a head up display app on your phone. These apps project information onto your windshield when you place your phone in the right spot on the dashboard. You’ll probably need a grippy mounting pad to keep your phone in place throughout the journey.
Best Head Up Display For Cars FAQ:
Q: What are HUDs for?
A: Head up displays (HUDs) are an alternative to conventional dashboard dials. They’re designed to make it safer and easier to see vital trip information by placing it at eye level. This means you don’t need to take your eyes off the road to read a speedometer, or check your mileage.
A: HUDs were originally developed for aviation purposes, but they’re just as useful to drivers on the ground.
They work by treating your windshield as a screen, and projecting images onto it. Sometimes, your windshield will need to be coated with a special film to make the display more easily visible.
Q: Are HUDs safe?
A: Yes, HUDs are safe to use. In fact, once you’re used to using one, your driving is likely to be safer than it was without. This is because a head up display allows you to keep a better eye on your speed, or navigation instructions, without having to look away from the road.
