The best OBD2 speedometers present vehicle speed and other operational data clearly, allowing drivers to quickly digest information without losing focus on the road. Standalone OBD2 speedometers often surpass built-in car HUDs in the range of data displayed, leveraging the OBD2 port to access a wealth of vehicle diagnostics. However, they typically do not integrate with car entertainment or navigation systems.
OBD2 speedometers vary significantly in design and functionality. Some primarily mirror dashboard readings, displaying speed and time, while advanced models offer tachometer, fuel economy, and more detailed OBD2 data. The most sophisticated units can even connect to smartphones for navigation and communication alerts, with top-tier models supporting Android Auto or Apple CarPlay for comprehensive integration.
When selecting an OBD2 speedometer, consider the following:
- Data Display: Ensure it displays the speed clearly and accurately. Additional OBD2 data parameters are a bonus for informed driving.
- Screen Type and Size: Choose between direct view screens and projection-based HUDs. Projection screens can offer larger virtual displays but may vary in visibility under bright conditions. Fold-down screens offer better clarity and can be stowed away when not needed.
- Connectivity: OBD2 connectivity is crucial for accessing vehicle speed and diagnostics. GPS adds location and speed accuracy, while smartphone integration expands functionality.
- Ease of Use: A user-friendly interface and straightforward setup are essential. Consider button layout and menu navigation for ease of operation while driving.
- Installation: Modern OBD2 speedometers are designed for easy setup, often within minutes. Cable management is a minor consideration, with flat cables being easier to conceal.
OBD2 Speedometer Cost Considerations
Entry-level head-up displays, often lacking OBD2 functionality or offering basic monochrome displays, can be found for under $20.
For a functional OBD2 speedometer with a good range of features, including color displays and multiple data parameters, expect to spend between $30 and $70.
High-end OBD2 speedometers, offering extensive features, smartphone integration, and premium designs, can exceed $250. These models provide the most comprehensive functionality, pulling data from multiple sources including OBD2 and smartphones.
How We Evaluate OBD2 Speedometers
Our OBD2 speedometer testing process combines garage setup with real-world driving assessments. Initial setup focuses on installation and optimal positioning to ensure the device is useful without obstructing the driver’s view. Wire concealment is also assessed for ease and tidiness.
Performance testing begins with startup and shutdown timing, evaluating how quickly the OBD2 speedometer boots up and displays speed and other data. Display sharpness and interface design are rigorously assessed for clarity and ease of use.
Real-world driving tests are crucial for evaluating the OBD2 speedometer’s effectiveness under various conditions, including different lighting and driving maneuvers. We assess how well the speedometer keeps pace with speed changes and maintains visibility. Special features, such as text displays or inclinometers, are also tested in practical driving scenarios to ensure their reliability and utility.
