Troubleshooting
If you encounter issues with your ASHOIH OBD2 HUD Display, please refer to the following common problems and solutions:
- No Display/No Power:
- Ensure the OBD cable is securely connected to both the HUD and the vehicle's OBD2 port.
- Verify that the vehicle's engine is running.
- Check the vehicle's fuse box for any blown fuses related to the OBD2 port.
- Inaccurate Speed/Data:
- Ensure the GPS signal is strong (if using GPS mode). Drive in an open area.
- Check settings for unit conversion (e.g., km/h vs. mph).
- Some vehicles may have slight discrepancies between dashboard speed and OBD2 speed. Adjust calibration in settings if available.
- Display Freezes/Unresponsive:
- Disconnect and reconnect the OBD cable to restart the device.
- If the issue persists, perform a factory reset through the device settings (consult the on-screen menu for this option).
- No GPS Signal:
- Ensure the device has a clear view of the sky. Metallic window tints or certain vehicle structures can interfere with GPS reception.
- Move the vehicle to an open area away from tall buildings or dense foliage.
If these steps do not resolve the issue, please contact ASHOIH customer support for further assistance.
