This manual provides comprehensive instructions for the iKiKin AP6 OBD2 GPS Dual Smart Gauge Car Head-Up Display. Please read this manual carefully before use to ensure proper installation, operation, and maintenance. This device is designed to enhance your driving experience by displaying crucial vehicle data directly in your line of sight.
2. Product Overview
Key Features
- Rich Data Display & Alarm: Offers 9 unlockable interfaces, displaying essential data such as speed, RPM, travel distance, coolant temperature, voltage, fuel consumption, satellite number, and turbo pressure.
- RGB Color Change Ambient Light: Features an ambient light that changes color based on driving conditions. It displays blue during normal operation and turns red during abnormal driving, such as rapid acceleration, to alert the driver.

5. Maintenance
To ensure the longevity and optimal performance of your iKiKin AP6 Head-Up Display, follow these maintenance guidelines:
- Cleaning: Use a soft, dry, lint-free cloth to clean the display screen and exterior. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the device's finish and screen.
- Storage: When not in use for extended periods, store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
- Cable Care: Ensure the OBD2 cable is not pinched or excessively bent, which could damage the internal wiring.
6. Troubleshooting
If you encounter issues with your iKiKin AP6, refer to the following troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on/No display | Loose OBD2 cable connection; Vehicle ignition off; Faulty cable. | Check if the OBD2 cable is securely connected. Ensure vehicle ignition is on. Test with another OBD2 device if possible to rule out cable issues. |
| Inaccurate speed/data readings | Incorrect unit settings (km/h vs mph); Poor GPS signal (in GPS mode); OBD2 incompatibility. | Verify unit settings in the device menu. Ensure the device has a clear view of the sky for GPS signal. If using OBD2, confirm your vehicle supports the protocol. |
| OBD2 functions not working, only GPS data displayed | Vehicle does not support OBD2 protocol. | This is normal behavior. The device automatically switches to GPS-only mode if OBD2 is not detected. No action required unless you believe your vehicle should support OBD2. |
| Device freezes or malfunctions | Temporary software glitch; Power fluctuation. | Disconnect the device from the OBD2 port, wait a few seconds, then reconnect. If the issue persists, perform a factory reset via the device settings (refer to on-screen menu). |
| Cannot clear fault codes | System not configured to clear DTCs; Underlying vehicle issue persists. | Ensure the 'Clear DTC' option is enabled in the device settings. Clearing a code does not fix the problem; address the vehicle's underlying issue first. |
