10 Best OBD II Scanners 2026 in the United States

The OBDLink MX+ is a versatile Bluetooth OBD-II scanner compatible with iPhone, Android, and Windows devices, making it an excellent choice for using your smartphone or PC as a car diagnostic tool. It works with many popular apps such as FORScan, Torque, and BimmerCode, providing access to detailed vehicle data beyond engine codes, including ABS, airbag systems, and tire pressure monitoring. The scanner also supports enhanced functions for several car brands like Ford, GM, Toyota, and Honda, which is advantageous for owners of these vehicles.

This compact device plugs directly into your car’s OBD-II port and draws power from the vehicle itself, eliminating the need for batteries. It includes built-in protections against over-voltage and battery drain, enhancing its reliability. Since the user interface depends on the app you choose, it offers flexibility but may require some trial to find one that fits your preferences. Firmware updates are available to maintain compatibility with newer vehicles and features.

Because it relies on external apps, the user experience can vary, and some advanced functions might require paid apps. Additionally, the scanner does not store data internally, so data logging depends on the capabilities of the connected device. This product fits well for car owners seeking deeper insight into their vehicle’s health with a straightforward Bluetooth connection and who are comfortable using smartphone apps for diagnostics.

Data management is enhanced by cloud storage options, so you won't lose diagnostic history, and the device supports recording and playback of live data for thorough troubleshooting. The scanner comes with 1-year free software updates, which keep it current with new vehicle models and functions, though renewing updates after 1 year involves an extra cost. Customer support is directly accessible via email, which is helpful if you encounter issues. Some advanced functions (e.g., battery testing, endoscope camera) require purchasing additional accessories. While the scanner supports many languages, language activation needs to be authorized through customer support.
