Key Features to Consider in an OBD2 Heads Up Display

The best OBD2 heads up displays present crucial vehicle data in an easily digestible format, right in the driver’s line of sight. Aftermarket OBD2 HUDs often surpass built-in systems in terms of the range of data they can display. However, they typically don’t integrate with the car’s infotainment or navigation systems.

OBD2 car head-up displays vary significantly. The information displayed can range widely. Some merely mirror basic dashboard readings like speed, while others offer advanced data like tachometer readings and fuel economy, all accessed through the OBD2 port.

Many OBD2 HUDs go further, displaying parameters that, while not essential for safe driving, can be highly interesting. These can include turbo boost pressure and altitude. For off-road drivers, certain OBD2 HUDs can even provide roll and tilt warnings.

The most advanced options might connect to your smartphone, displaying navigation prompts, contact details, and even messages. At the high end, some OBD2 HUDs offer Android Auto or Apple CarPlay support, upgrading older vehicles lacking these features.

Regardless of design and features, an OBD2 heads up display’s primary function is to show desired data without distracting the driver. Screen size is a crucial factor. Larger screens enhance readability but can also obstruct vision. Smaller screens are less obtrusive but might be harder to read at a glance.

OBD2 HUDs employ different display technologies: direct displays and projection systems. Direct displays are generally larger, while projectors create a virtual image that can appear larger (up to 10 inches). Projected images can suffer from visibility issues in bright sunlight.

Projector-based OBD2 HUDs with fold-down screens offer improved clarity compared to windshield projection. The fold-down screen can also be tucked away when not needed.

Color displays are highly beneficial, allowing designers to present more information within a smaller area. Button layout is also critical. Simple, intuitive controls are essential for easy menu navigation and setting adjustments.

Finally, consider data and power sources. OBD2 ports provide access to a wealth of vehicle data, though perhaps not as comprehensively as a dedicated OBD-II scanner. GPS adds data like distance and altitude. GPS-only units require separate power, often from a car’s 12V outlet.

Installation of modern OBD2 HUDs is typically quick and easy, often taking only minutes. The most challenging aspect can be concealing the wiring, but flat cables can simplify this. Most units mount on the dashboard using adhesive pads or strips.

OBD2 Heads Up Display Pricing

Entry-level OBD2 heads up displays can be found for under $20, but quality is often compromised. These may have monochrome displays or limited data presentation, often just speed.

Stepping up to the $30-$70 range significantly expands options, offering a wide selection of functional OBD2 heads up displays. High-end OBD2 heads up displays can exceed $250, but these are less common.

The higher price reflects advanced features, stylish designs, and the ability to integrate data from multiple sources, including OBD2 and smartphones.

Our OBD2 Heads Up Display Testing Methodology

Our OBD2 heads up display testing involves both garage setup and extensive on-road evaluation. Initial setup and positioning are crucial, ensuring the display is both useful and doesn’t obstruct the driver’s view. Wire concealment is the next step, ensuring wires are long enough and securely routed.

We conduct startup and shutdown timing tests, measuring how quickly each OBD2 HUD boots up and displays data after engine start and how long it takes to shut down after engine off.

Display sharpness and interface design are assessed, along with the ease of use of controls and menu navigation. We systematically explore all settings and options.

On-road testing is critical to evaluate real-world usability. We assess display visibility in various lighting conditions and during different driving maneuvers to gauge data responsiveness.

Finally, we test specialized features, such as text display, inclinometers, and navigation, where available, to provide a complete picture of each OBD2 heads up display’s performance.
