4. Setup and Installation
Follow these steps to install your JTLB AP 6 Smart Gauge Display:
- Locate the OBD2 Interface: The OBD2 interface is typically found on the driver's side, approximately 30cm (11.8 inches) from the center of the dashboard. Refer to your vehicle's manual if you cannot locate it.
- Connect the OBD Cable: Turn off the vehicle's ignition switch. Connect one end of the provided OBD cable to the vehicle's OBD2 interface.
- Connect to Smart Gauge: Connect the other end of the OBD cable to the OBD interface on the smart gauge.
- Route the Cable: Carefully hide the OBD cable, for example, along the A-pillar, to ensure it does not interfere with driving.
- Power On: Turn on the ignition switch. The device should power on and begin operation.
Important Notes:
- If your car is not compatible with OBD (e.g., electric vehicles, pickup trucks, RVs, or certain modified vehicles), please use GPS mode. This OBD HUD does not support JOBD and OBDI protocols.
- If you are unsure about your car's compatibility, consult with the manufacturer before purchase.

5. Operating Instructions
5.1 Dual System Operation (OBD + GPS)
The AP 6 features both OBD and GPS modes. The device will automatically detect the connection type. If OBD is not compatible, it will switch to GPS mode.
- OBD Mode Display: Speed, water temperature/oil temperature, voltage, fuel consumption, RPM, mileage, driving time, satellite number, altitude, turbine pressure, acceleration test, brake test, and other vehicle data.
- GPS Mode Display: Speed, voltage, driving time, altitude, number of satellites, driving direction, simple mileage.
5.2 Ambient Light Function
The device includes an LED ambient light with the following functions:
- Normal Operation: The light illuminates blue after booting, adjusting its brightness based on the surrounding environment.
- Alarm State: When an alarm is triggered, the light turns red and flashes, maintaining its brightest state for clear visibility.
- Brightness Adjustment: The brightness can be manually adjusted or turned off. Even if turned off, it will still flash red during an alarm.

5.3 Customization and Unit Switching
In OBD mode, you can customize the small icons displayed according to your preferences. You can also switch units:
- Switch between miles and kilometers for speed and distance.
- Switch turbine unit to PSI, Bar, or 100KPA.
