Heads up dashboard displays (HUDs) are some of the most fascinating driver adaptive technologies available today. And while they lack the novelty of lane departure and blind spot warning systems, they’re more indispensable for everyday driving safety than any other system of their kind.
Unlike the bulk of today’s Eyes-on-the-Road-Benefit (ERB) systems, dash-mounted HUDs don’t require costly cameras and sensors, or the complex integration that other technologies require. That’s because they don’t actually need to be hard installed in the vehicle they’re used with. All an owner needs is a portable aftermarket HUD module and a connection to their vehicle’s OBD or OBD2 port, and they can instantly enjoy all the advantages a HUD has to offer in any vehicle, be it a car, truck or RV.
Codebreaker HUDs Put Driver Data Where It’s Needed

Let’s be honest, while most car and truck owners have at some point questioned the way technology has taken over even the simplest automotive functions, aftermarket head up displays are the type of adaptive systems that every driver can benefit from.
These compact, easy-to-setup modules are designed to give drivers the situational awareness they need to monitor a full range of dashboard indicator and function readings without taking their eyes off the road. And with their uncompromising accuracy and portability, they bring the same level of heads-up driver safety and certainty that’s found in many of the highest end vehicles manufactured over the last 30 years.
Australia’s Ultimate9 is a pioneer in cutting-edge portable heads up display module development. And their groundbreaking lineup of Codebreaker GPS, and OBD / OBD2 head up displays are standouts in portable data projection, with features that include:
- 50-150km/h speedometer and accelerometer readings, accurate to within 3–6km/h;
- Engine coolant temperature and battery voltage readings;
- A multi-direction compass that refreshes anytime the vehicle exceeds 5km/h;
- Adjustable over-speed, high coolant temperature, and abnormal voltage alarms; and,
- 150km/h over-speed alarm, with a 4 hour fatigued driving reminder.
When weighing the value of HUDs like the Codebreaker, it’s important to consider that a high-quality automotive heads up displays module is as notable for what it doesn’t do as for what it actually does. While many OE automotive heads up displays boast about their ability to project text messages, navigation maps, and a host of other data points onto the windscreen, they also have the ability to bring on dangerous cognitive overload. By only providing data that’s necessary to keep drivers and their vehicles safe, Codebreaker head up display modules are engineered specifically not to overwhelm drivers with data.
Three Codebreaker Models Built For Every Contingency

Along with their accuracy and compact size, versatility is what sets Codebreaker automotive HUD display modules apart from competing aftermarket displays. And in a market that’s dominated by single-dimension displays that are either too small to be practical, or so large that they obscure the view of the road, Ultimate9 understands that there’s no such thing as one size fits all when it comes to HUDs.
Ultimate9 sells three versions of its Codebreaker vehicle HUD display, each with its own core of versatile attributes:
- The wireless OBD HUD Speedometer. This plug-and-play HUD for cars utilises a wireless transmitter connected to a vehicle’s OBD port to send core dashboard information to the unit’s combination solar-, or USB-charging speedometer.
- The multi-functional OBD2 HUD. Full-functionality OBD2 automotive HUD modules are designed to connect directly to a vehicle’s OBD2 port, and to project a wide range of dashboard and engine performance data onto a reflective film that resides on the windscreen.
- The zero-connection GPS HUD. Codebreaker’s GPS heads up display for automobiles is powered directly from a vehicle ignition source, and utilises the pinpoint accuracy of satellite navigation to project GPS-calculated speed, speed alarm, and direction of travel data onto the windscreen.
And although Codebreaker is available in three different variations, they’re all equally committed to helping drivers avoid costly fines and demerits due to speeding, ensuring their attention remains firmly on the road, and reducing the dangerous tendency to drift when looking away from the road. The Codebreaker’s anti-glare film also gives it the edge when it comes to preventing visibility problems in direct sunlight, as well as reducing eye fatigue at all times.
Codebreaker Exercises the Mastery of Miniaturisation
Whether it’s in their higher electronic processing speeds, or their greater signal integrity, miniaturisation is the key driver behind portable driver assistance systems like Codebreaker automobile HUD modules. That’s why there’s no way to discuss the Codebreaker’s compact size or its premium circuitry without acknowledging the role that miniaturisation plays in their construction.
The fact is, most aftermarket head up displays unit manufacturers lack Ultimate9’s expertise when it comes to miniaturisation. And starting with the 86mm x 37mm x 16mm dimensions of the Codebreaker OBD2 and GPS, and the ultra-compact 50mm x 50mm x 50mm dimensions of the standard Codebreaker OBD, the benefits of their mastery of miniaturisation are evident:
- The Codebreaker’s advanced internal circuitry is designed specifically for processing ported OBD/OBD2, and GPS data, and formatting it for display;
- Each Codebreaker features a display element that’s engineered especially for image projection, along with a choice of either white and red, or green backlighting colours; and,
- The Codebreaker’s advanced light sensor is designed to allow both manual, and automatic brightness adjustments.
And with their UV-resistant ABS housings, Codebreaker vehicle heads up display modules are built to endure dashboard temperatures as high as 80°C. Their circuitry is fully protected, making the Codebreaker the kind of head up display Australia can trust to withstand the country’s toughest conditions.
The Final Word
At the end of the day, portable aftermarket HUDs are more than just thoughtful versions of their built-in counterparts. When properly designed and smartly utilised, they can place a wide range of vital operating data precisely where drivers want it, all without the headache of a complex installation.
Ultimate9’s family of OBD-compatible Codebreaker HUDs have everything a car, truck, or RV owner needs to keep track of their vehicle’s performance while keeping their eyes on the road. They offer the ERB advantage that matters the most.
