- Voltage: Vehicle battery voltage.
- Fuel Consumption: Real-time fuel usage, sometimes with a progress bar.
- Time: Current time.
- Mileage/Driving Distance: Distance traveled during the current trip.
- Travel Time: Duration of the current trip.

Multiple Data UI Interfaces
The MAIMEIMI OBD2 Head Up Display offers 9 distinct data UI interfaces. These interfaces allow you to customize the display to show single or multiple driving data points simultaneously, according to your preferences and driving needs. Refer to the image below for examples of available layouts.
Alarm Functions
The device includes 5 alarm functions designed to enhance driving safety by alerting you to critical conditions. You can adjust the alarm thresholds according to your preferences and local regulations. The HUD will emit an audible alert if any preset value is exceeded.
- Overspeed Alarm: Alerts you when your speed exceeds a set limit.
- Voltage Alarm: Notifies you if the vehicle's voltage drops below a safe level.
- RPM Alarm: Warns if engine RPMs exceed a predefined threshold.
- Water Temperature Alarm: Indicates if the engine coolant temperature becomes too high.
- Fatigue Driving Alarm: Reminds you to take a break after a set period of continuous driving.
Automatic Brightness Adjustment
The HUD features a built-in light sensor that automatically adjusts the display brightness based on ambient light conditions, ensuring clear visibility day or night. Manual brightness adjustment is also possible through the device settings.
Troubleshooting
Speed Inconsistency Adjustment
If you observe a discrepancy between the HUD's speed reading and your vehicle's speedometer, follow these steps to calibrate the HUD:
- Enter setup mode 1 on the HUD. The initial value displayed is typically 107.
- Compare the HUD speed with your vehicle's speedometer. For example, if your vehicle's speedometer reads 100 MPH and the HUD reads 105 MPH (meaning the HUD is 5 MPH faster), you need to adjust the HUD's value.
- Subtract the observed speed difference from the initial value. In the example, 107 - 5 = 102. Adjust the HUD's setting to 102.
- This adjustment principle involves adding or subtracting the speed difference from the initial calibration value (107) to match your vehicle's speedometer.
