Key Features to Consider When Choosing an OBD2 Heads Up Display
The best OBD2 heads up displays excel at presenting crucial vehicle data in a format that is instantly understandable and easily viewable without taking your eyes off the road. Standalone OBD2 HUDs often surpass built-in car HUDs in the breadth of data they can display, leveraging the wealth of information available through your car’s OBD2 port. However, they typically do not integrate with in-car entertainment or navigation systems.
When evaluating OBD2 car heads up displays, several factors are paramount:
OBD2 Data Parameters: The core advantage of an OBD2 HUD is its access to your car’s computer. Look for HUDs that display the OBD2 parameters most relevant to you. Common and useful parameters include:
- Speed (MPH/KPH): Essential for safe driving and monitoring speed limits.
- RPM (Engine Revolutions Per Minute): Useful for performance driving and monitoring engine load.
- Coolant Temperature: Critical for preventing engine overheating.
- Battery Voltage: Indicates the health of your car’s battery and charging system.
- Fuel Consumption/Economy: Helps optimize fuel efficiency.
- Turbo Boost Pressure (for turbocharged vehicles): Performance metric for turbo engines.
- Air-to-Fuel Ratio: Advanced engine diagnostic parameter.
- OBDII Fault Codes: Allows you to read and potentially clear engine trouble codes.
Display Type and Clarity: OBD2 HUDs use different display technologies:
- Projected Displays: Project information onto the windshield or a reflective screen. Projection onto a fold-down screen generally offers better clarity, especially in bright sunlight.
- Direct View Displays: Data is shown directly on a transparent screen. These tend to be larger but eliminate projection issues.
Consider screen size and brightness. Larger displays can improve readability, but ensure the HUD’s size doesn’t obstruct your view. Color displays are generally preferable as they can present more information effectively and are easier to interpret at a glance.
Features and Functionality: Beyond basic OBD2 data display, consider these features:
- Alarms: Configurable alarms for speeding, high engine temperature, low voltage, etc., enhance safety.
- GPS Integration: Combines GPS data for speed, location, and sometimes navigation.
- Smartphone Integration: Some high-end OBD2 HUDs offer limited smartphone integration for notifications, though full Android Auto/Apple CarPlay integration is rare in aftermarket HUDs.
- Installation and Setup: Most OBD2 HUDs offer plug-and-play installation via the OBD2 port. Ease of setup is a key factor for user-friendliness.
Size and Design: The physical size and design of the OBD2 HUD are important. Ensure it fits well on your dashboard without obstructing your view. Consider the cable management – a flat cable can be easier to conceal.
Cost of OBD2 Heads Up Displays
Entry-level heads up displays, often lacking OBD2 connectivity or offering very basic monochrome displays, can be found for under $20. However, for a functional OBD2 heads up display with color, multiple data parameters, and reliable performance, expect to spend between $30 and $70.
High-end OBD2 HUDs, offering advanced features, brighter and larger displays, and integration capabilities, can range from $100 to over $250. These premium models often justify their price with superior performance, more extensive data displays, and better build quality. Investing in a mid-range to high-end OBD2 HUD generally provides the best balance of features and reliability.
