Best HUD for a Car – Buyer’s Guide

It may seem like Star Trek technology, but automotive HUDs have been with us for a while. In fact, HUD displays made their first appearance in fighter jets.

Of course, since that time, the technology has advanced and become more readily available for consumer use. While some auto manufacturers are starting to include a HUD in their newer vehicles, there are still plenty of solid aftermarket options.

Choosing the Best Car HUD of 2018

1. Kivic – The Best New HUD of 2018

For anyone who’s new to heads-up displays or HUDs just know that the general purpose of having this device is to allow you to keep your head up and eyeline on the road, as you view statistics such as your speed, time as well as GPS and just about anything that appears on your phone.

The Kivic is one such gadgets. According to the instruction manual, the Kivic HUD beams the various contents on the road in front of the driver by connecting with Android-based smartphones and iPhones wirelessly.


The driver can check information such as the time, vehicle speed, messages, incoming calls and GPS information while driving. A key feature of Kivic is that all display information comes from your phone without relying on an OBD2 connection.

You could use this device with any vehicle regardless of whether it is an OBD2 compatible, including cars made prior to 1996 (the year that cars had to be obd2 compliant). The new Kivic HUD comes with a handful of parts: mounting bracket which was already in place, the wire clip, power cable, cigar charger and a user manual.


The main device consists of the display engine, the combiner, locking lever, power USB, and a light sensor. With the locking lever, we can make slight adjustments, so it’s easy to adjust a better view of a display.


What it’s like to use a Kivic? Installation was incredibly easy. Just push the sticker. Center the Kivic on a dashboard in the middle of a cluster panel and plug it into the cigar lighter.

One thing I would have liked to have seen is an extra USB out on the Kivic charger so that it would be possible to keep a phone charged while using. There are plenty of cars on the road that still only have one cigar lighter socket next to the driver. Something like this would have been nice and I think Kivic looks nice in a car. It’s sleek and feels appropriately placed, so the last step is to download the app. All options were pretty self-explanatory and once I hit a button it immediately began to display information. Bluetooth was already turned on and this part of the process felt quite easy.

In Real Life

You’ll also receive notifications when someone calls or texts or when someone contacts you via Facebook. When receiving calls you still need to rely on things like a Bluetooth earpiece or placing your call on a speaker and when receiving a text you should use voice commands to both listen and respond. Full-screen mode and screencasting will allow Kivic to show whatever image your phone is currently displaying.

Screencasting ability for reading text or even playing videos would not be safe, and even if it somehow is, it would not be an enjoyable experience. You have to train your eyes on words or video, so you lose the main benefit of having the Kivic which is about of improved safety.

Just one exception to this would be the GPS. Running the GPS on Kivic is one of its strongest benefits. I use GPS daily even on familiar commutes to check the traffic conditions and having my eye line on the Kivic display feels much safer even compared to having a phone holder on a dashboard.


It’s easy to see the road through the glass display. It removes tension that comes with each glance away from the road. The display is suitably bright during the day and there’s no trouble viewing time in miles per hour and at nighttime. Definitely, a great gadget for its price.

  • Display Size and Picture Quality
  • Fair Price
  • Screen Casting Support
  • Doesn’t Require OBDII
  • Solid Design
  • No Extra USB for Charging Phone
  • User Interface Should be Simplified

2. Garmin – The Best Mid-Tier Aftermarket HUD

While the Garmin cannot come close to competing with the Navdy in terms of functional robustness, it does still provide far more versatility and options than any other product on this list and does so at a much lower price point than the Navdy. In fact, the Navdy is at least 3 times more expensive than the Garmin and may be more than that depending on the supplier.

However, one area where the Garmin provides a unique feature that the Navdy cannot match is screen versatility. Whereas the Navdy uses a dedicated screen, the Garmin is able to use both a dedicated screen or a film projection. While a dedicated screen is without question better for image quality, smaller cars or those with a lower angle windshield slope may have trouble accommodating the HUD and screen without seeming awkward, unsightly, or just not fit properly.

Moreover, while the Garmin does not feature the same breadth of 3rd-party app compatibility as the Navdy, it does use a proprietary app that allows GPS and directions – though in a more limited context. The Garmin also accomplishes this connectivity via Bluetooth, just like the Navdy.

In Conclusion

Unfortunately, that is where a number of the favorable comparisons end. One big issue with the Garmin is the requirement that the app remain at the foreground of your phone while in use. ASide from the limitations this places on its use, it also means that the HUD will literally cut off if you receive a phone call or check a text message. Moreover, the onboard GPS and directions of the Garmin are far inferior, often not entirely accurate or precise.

  • Only the Garmin HUD gives you the versatility to choose whether you want to use the included lens or a film on your windshield as the display
  • The HUD’s power adapter can also be used to charge a phone with a USB connection
  • The only other HUD on our list that offers directions, though more simplified than the Navdy’s
  • Though not as expensive as the Navdy, the Garmin is still far more expensive than the other three products on this list without all of the Navdy’s features
  • The information will be shut down should you use your phone for another purpose during its activity
  • The direction information is not as accurate as one would like and must come from the Garmin HUD app itself

3. Arpenkin X5 HUD – The Best Budget HUD

This aftermarket HUD is a barebones product. Keep in mind, there are many people who have no interest in all of the other pieces of information that the other HUDs on this list provide. In fact, there are numerous customers who have purchase some of the other products that noted they specifically used tape to block out some of the unwanted clutter to better focus on only the information they were interested in.

Of course, this can be a bit of a double – edged sword. While the total amount of information the HUD can display is not truly compromised, and numerous users will appreciate the displaying of a single piece of information at once, switching through the different pieces of information can be tedious and ultimately takes your eyes off of the road.

Moreover, this HUD features the worst display out of any on our list, and there are no ways to correct it like with some of the other products we reviewed. The Arpenkin, as a budget HUD, uses a projection display onto a film placed on your windshield. Unfortunately, this film does little to alleviate the problems common with many projection HUDS.


If you are using the Arpenkin during the daytime – regardless the angle of the sun or whether it is overcast – expect your image to seem dim and the resolution to get fuzzy. If you are driving directly towards the sun, the image will disappear altogether. Moreover, most modern windshields use a type of polarized glass that makes the image split into two.

Some of the other products on this list who suffer this issue have a workaround by placing a black film behind the screen. Sadly this does not work with the Arpenkin, which makes this only suitable for nighttime driving.

  • Though the difference is not significant, this is still the least expensive product on our list
  • The alarms are accurate, numerous, and easily customizable
  • The display information is well-organized and not at all cluttered
  • At 3”m this HUD has the smallest display out of any product on our list
  • Film projections without the option a lens can suffer from resolution and brightness issues as well as double image depending on the angle of the sun
  • The amount of information displayed is least amount out of any product on our list

4. ZXLine A8 – The Largest HUD Display

After the Navdy and the Garmin, this is probably the best HUD for most people – assuming it works for you vehicle. Unfortunately, the ZXLine was designed to work primarily in newer model vehicles. This means if your vehicle is 7 years old or older, there is a good chance the ZXLine simply will not function. To make matters worse, the English translation of the directions were written by a non-native speaker of English. As such, they are often confusing, it not outright contradictory.

However, if you have a newer model vehicle and are not looking to spend over $100 on an aftermarket HUD, the ZXLine will perform better than either the Echoman or the Arpenkin. However, both of those other models have clear advantages in some respects, so you will need to weigh what it is you want most.

Still not bad for the money

For instance, the ZXLine features the largest display out of any product on our list – including the Navdy. However, this display is limited to a projection which is less than ideal. Still, the ZXLine’s film does at least perform fairly well – especially compared to the other options. Of course, it is still not as clear or bright as a dedicated screen and will suffer some depending on the conditions of the sky.

One issue that is a bit of a push-pull consideration is the information organization. Quite simply, there is a fair amount of information, and it is all bunched together. This cluttered organization can make it somewhat difficult to see quickly. However, the ZXLine did at least color code the information to make it easier to see what you are looking for. Still, people with poorer eyesight might find it difficult to use.

  • At 5.5”, this HUD has the largest display out of any product on our list
  • The projection film does actually eliminate double images, unlike some other products
  • While the amount and organization can be a bit cluttered, the color coding helps find the information you are looking for quickly
  • Film projections without the option a lens can suffer from resolution and brightness issues depending on the angle of the sun
  • The directions are not well-written which can make installation difficult
  • This product faces the most compatibility issues out of any on our list

5. Navdy – Simply the Best Last Year’s Aftermarket HUD

The Navdy is the unquestioned champion of the aftermarket HUD arena. Is accomplishes this feat on all levels and by providing a product which can accomplish tasks that are simply non-existent outside of it. Of course, all of these advantages come at a premium price which is by and far the most expensive product on our list many times over. Still, if you are looking for the best aftermarket HUD available, this is the only game in town.

First, the Navdy features a dedicated screen that uses LED lights in full color. Quite simply, there is not another product on our list that can hope to compete with the brightness, clarity, and cohesion of image quality. The only issue is that the screen’s supposed transparent projection which is supposed make the image seem superimposed into the distance does not work for everybody. However, this is less of an issue with the product and more a result of different people’s biology not responding to the technology the same.

Other Features

Beyond the display, which is good enough on its own to make this the top HUD on our list, the information, connectivity, and interactivity of the Navdy presents a product that will be difficult to beat even years into the future. The Navdy syncs with your smartphone via Bluetooth. Moreover, while it does require the use of a proprietary app, that app can sit in the background and still function.

This allows the Navdy to use numerous 3rd-party apps or other apps on the phone without issue and will not interrupt the products function like it would with the Garmin. As icing on the cake, the Navdy can even respond to voice commands–though the effectiveness is a bit spotty – or hand gestures. With these interactive functions, you can answer calls, respond to texts, and get directions in real time.

  • Unmatched in terms of connectivity and interactivity such that the competition pales in comparison
  • The software is incredibly well done, presenting a far greater accuracy and responsiveness than the other products
  • Installation is a breeze and customer service is by far the most responsive
  • The display does not project directly onto your windshield, forcing you to continuously refocus as you look from the road to the HUD and back.
  • The image is incredibly dependent on the angle of observation such that if you move slightly to one side or the other–say you lean on the armrest–the image will go out of focus
  • There are a couple issues this HUD has with all-electric and hybrid vehicles specifically

6. Echoman EM03B – The Best HUD for Mountainous Driving

The Echoman holds a unique position on this list. While it does utilize a dedicated screen on which to project its display, the screen is definitely inferior to both the Navdy and the Garmin. Of course, using a screen, it is still superior to simple projection displays. Unfortunately, this does not prevent some of the same issues as projection displays which is a bit troubling. However, many users have found that by placing an opaque sheet behind the screen, these issues are completely resolved. Still, this requirement speaks to a larger issue the Echoman presents throughout its use: poor design.

For one, the display does present a good amount of information. In fact, the Echoman is unique in that it is the only HUD on our list that presents your altitude. In fairness, the Navdy could be used to find that information as well, but it is not presented natively. As such, if you are driving over mountainous terrain – like in Japan where the Navdy was developed – you will be able to see your altitude.

Unfortunately, both the altitude and the compass – the other piece of information not often found on a HUD – have their own issues. For some reason, these features regularly find themselves out of sync and must be realigned regularly. However, the HUD does not present the method for doing so in an easy manner and is not even necessarily effective once you do figure out how to change it.

Some Issues

Another issue with the information is its real-time reaction. If you speed up or rev your engine, there is a 1-3 second delay before the HUD responds. This also applies to changes of altitude and direction. For long-driving, this is not an issue. However, city driving requires constant change to these qualities, leaving you essentially with a range and not an exact figure.

  • This is the only HUD that provides an altitude
  • Installation is fairly easy and straight-forward, though some of the settings are more difficult to adjust
  • Reasonably priced and provides a good amount of information
  • The actual arrangement of the information is not especially ordered or attractive
  • The information output has a bit of a delay, which can be especially important for things like speed
  • Both the compass and the altitude will need to be reset often and is a tedious process in the first place

Best HUD for a car – Buyer’s Guide

There are only two types of aftermarket automotive HUDs at the moment: projections and screens. Ultimately, the HUDs that utilize their own screen are generally superior.

The screen itself allows you to quickly and easily reposition the unit if the angle does not allow the best presentation. Moreover, HUDs with their own screen are far more likely to suffer less from the dreaded “double image.”

However, the material of the screen will play an important role in whether this effect occurs as well. However, there is no standard material used for HUD displays that use a screen, though avoidance of plastic composites is advisable. Unfortunately, the HUDs that utilize a screen are also generally significantly more expensive than HUDs that simply project the image.

Problems and Solutions

Still, you get what you pay for, and projection HUDs have their own issues. The biggest problem with projection HUD has to do with the image quality. In the most ideal conditions, the image quality of a projection HUD will generally be pretty good. However, ideal conditions are usually limited to at night without too many bright lights. During the day, and especially if the sun is in front of you setting on the horizon, the image of projection HUDs can be completely washed out.

Moreover, projection HUDs are also far more likely to suffer from double vision, regardless the light conditions, than HUDs with a dedicated screen. Whether or not this occurs and the extent to which it does has to do with the type of glass and construction of your windshield as well as the material used for the film on which the image is projected.

This also requires you to stick a small piece of film onto your windshield which can be difficult. Specifically, you need to know exactly where the film should be placed which can take a few tries of trial and error. Moreover, depending on the HUD, the film itself may be sticky. This can make removing it from the windshield difficult, and if you have to reposition it numerous times, it may lose some of its adhesive integrity.

Connectivity and Information

Most HUDs still connect by way of wires. This is especially relevant for the HUD’s ability to display the vehicle’s performance. Moreover, many HUD’s are also powered by the 12 volt vehicle outlet located on your dash. However, if your HUD connects to your smartphone, it may require another stage of connectivity. In this regard, the HUD may connect directly to the smartphone with a cable, or it may allow connection through Bluetooth.

Whether or not your HUD connects to your phone will also impact the amount and type of information you can receive. HUDs that do not connect to a smartphone generally only receive information from the vehicle itself. This information can include, speed, RPMs, engine temperature, and a host of other pieces of information. However, if your HUD connects to your phone it will often provide directions when driving, and some of the more advanced HUDs will even allow you to use 3rd-party apps.

Display Quality

This consideration can broken down into 3 qualities: brightness, resolution, and cohesion. Cohesion in this instance relates to whether or not the display creates a double-image effect or not. Generally, it is the polarization of windshields that cause this effect. The brightness will have a lot to do with the type of illumination–with LED being the brightest.

However, the brightness will also hinge on whether the display is projected onto a dedicated screen or a film placed on the windshield.

The same considerations which impact the brightness of the display will also impact the resolution and the cohesion with the same factors producing a better or worse quality.


This consideration can be broken into two parts: smartphone and vehicle. The best HUDs connect to your smartphone and even allow the use of 3rd-party apps while in function. However, even for the HUDs that connect to your smartphone, many of them require the use of HUD-specific apps and may stop working when you switch to a different app.

The other compatibility consideration for HUDs has to do with the vehicle in question. Different vehicles have different readout systems which measure the vehicle’s performance. These readouts are OBD, OBD II, EOBD (for European standards), and JOBD (for Japanese standards). If your HUD and vehicle readout are not compatible, you will not be able to receive information about your vehicle’s performance through the HUD.


If money is no issue, the Navdy is the only option that can provide a full modern experience. Aside from its impressive dedicated screen size, it also presents more information than any other product on our list.

Of course, this has to do more with the Navdy’s ability to connect with your smartphone and utilize 3rd-party apps, but it is still an impressive feat to be able to control your smartphone with hand motions directed towards your HUD.

Beyond the Navdy, the Garmin offers a decent product at a greatly reduced price, though the smartphone functionality is greatly reduced as well. For a stripped down, budget option, the Arpenkin is a solid choice, though the ZXLine may be a better one.
