Display Functions:
- Speed (MPH/Km/h): The central and most prominent display shows your current driving speed. The unit (MPH or Km/h) can be switched.
- Driving Direction (Compass): Indicates your current cardinal direction (N, S, E, W).
- Driving Time: Displays the duration of your current trip.
- Driving Distance: Shows the distance covered during your current trip.
- Clock: Displays the current time.
- Altitude: Shows your current elevation.
- Number of Satellites: Indicates the number of GPS/BeiDou satellites the unit is currently connected to, affecting accuracy.
- Acceleration Time: Measures acceleration over a certain distance (e.g., 0-100 km/h).
Automatic Light-sensitive Adjustment:
The G17 features an integrated light-sensing system that automatically adjusts the screen's brightness. This ensures optimal visibility in bright daylight and prevents excessive brightness during nighttime driving, providing a comfortable visual experience without manual adjustment.
Alarm Functions:
The device includes two important alarm functions to promote safer driving:
- Overspeed Alarm: You can set a multi-stage overspeed alarm. When your vehicle exceeds the preset speed limit, the device will provide an audible and/or visual alert.
- Fatigue Driving Reminder: After 8 hours of continuous driving, the device will issue a reminder to encourage the driver to take a break, helping to prevent fatigue-related accidents.

Maintenance
To ensure the longevity and optimal performance of your BY-J G17 GPS Speedometer, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe the display and exterior of the unit. Avoid using abrasive cleaners, solvents, or spray cleaners directly on the device, as they may damage the screen or casing.
- Storage: When not in use for extended periods, store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Handle the unit with care. Avoid dropping it or subjecting it to strong impacts, which could damage internal components.
- Cable Care: Ensure the USB connection cable is not kinked, pinched, or placed under heavy objects, as this can damage the cable and affect power supply.
Troubleshooting
If you encounter any issues with your BY-J G17 GPS Speedometer, please refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Display / Unit Not Powering On | No power supply; loose USB connection; faulty USB port/charger. | Ensure the USB cable is securely connected to both the G17 and a working USB power source (5V). Try a different USB port or car charger. |
| No Speed Reading / Inaccurate Speed | Poor GPS signal; unit not acquiring satellites; vehicle stationary. | Ensure the vehicle is outdoors with a clear view of the sky. Drive for a short distance to allow the unit to acquire GPS signals. Avoid areas with tall buildings or tunnels that block satellite signals. |
| Display Too Bright/Dim | Automatic light sensor adjustment. | The unit features automatic light-sensitive adjustment. This is normal operation. If it seems stuck, try restarting the device by unplugging and re-plugging the USB cable. |
| Alarms Not Functioning | Alarm settings not configured; audible alarm switched off. | Refer to the device's specific settings (if accessible via buttons, though not detailed in provided data) to ensure overspeed limits are set and the audible alarm is enabled. |
