Storage: If storing the unit for a long time, disconnect it from the vehicle and keep it in a cool, dry place.
Cable Care: Ensure the OBD cable is not pinched or excessively bent, which could damage the internal wiring.

6. Troubleshooting

If you encounter issues with your HUD unit, refer to the following common troubleshooting steps:

Problem	Possible Cause	Solution
No display/Unit not powering on.	Loose OBD connection, vehicle's OBD port issue, unit malfunction.	1. Ensure the OBD cable is securely connected to both the HUD and the vehicle's OBD2 port. 2. Check if your vehicle's OBD2 port is functioning correctly (e.g., by connecting another OBD device). 3. Try pressing the power button on the unit.
Inaccurate speed reading.	Speed calibration needed, GPS signal interference.	1. Access the unit's settings menu to calibrate the speed according to your vehicle's actual speed. 2. Ensure the unit has a clear view of the sky for optimal GPS signal reception.
Unit frequently switches to GPS mode.	OBD connection issues, vehicle not fully OBD2 compliant.	1. Verify the OBD cable connection. 2. Some older or non-standard vehicles may have limited OBD2 compatibility; GPS mode is a suitable alternative.
Display is too dim or too bright.	Brightness settings.	1. Adjust the brightness manually through the unit's settings menu. 2. Ensure the automatic brightness sensor (if applicable) is not obstructed.
