X300 OBD 3-in-1 Multifunctional Vehicle Gauge with GPS

Monitor essential vehicle data, GPS speed, pitch, roll, and G-force on one dedicated display.

The X300 OBD2 gauge display connects directly to a compatible vehicle’s OBD-II port and provides real-time access to data such as RPM, vehicle speed, battery voltage, engine load, intake air temperature, fuel level, fuel rail pressure, and exhaust gas temperature.

With GPS + BeiDou positioning, multiple customizable display modes, an inclinometer, and a G-force meter, the X300 is designed for supported Toyota, Mitsubishi, Jeep Wrangler, Ford F-150 Raptor, and other compatible OBD-II off-road vehicles.

Key Benefits

• Real-Time OBD-II Data: Monitor RPM, speed, battery voltage, MAP, engine load, temperature, fuel-related data, and more.
• GPS + BeiDou Positioning: View GPS-based speed and positioning information.
• Off-Road Inclinometer: Monitor vehicle pitch and roll on uneven terrain.
• G-Force Display: View acceleration and directional force changes.
• Multiple Screen Modes: Switch between OBD gauges, GPS mode, cruise mode, inclinometer mode, and customizable data pages.
• Touch Controls: Swipe between screens and double tap compatible areas to change displayed data.
• Dedicated Display: Keep essential vehicle information visible without occupying your smartphone.

Displayed data varies by vehicle model, ECU configuration, OBD-II protocol, and supported PID output.

The X300 OBD2 gauge display combines real-time vehicle data, GPS-based driving information, off-road attitude monitoring, and customizable display modes in one compact screen.

Designed for supported off-road vehicles, pickups, SUVs, and performance-oriented vehicles, the X300 connects to the vehicle’s OBD-II port and displays available data directly from the vehicle’s electronic control system.

It is suitable for select Toyota, Mitsubishi, Jeep Wrangler, Ford F-150 Raptor, and other compatible OBD-II vehicles. Compatibility and available data depend on the specific vehicle, model year, ECU, protocol, and supported OBD-II PIDs.

Real-Time OBD-II Vehicle Data

The X300 displays multiple live vehicle parameters received through the OBD-II connection.

Depending on vehicle support, available data may include:

• Engine Speed — RPM
• Vehicle Speed — SPEED
• Battery Voltage — BATT
• Manifold Absolute Pressure — MAP
• Engine Load — LOAD
• Intake Air Temperature — IAT
• Fuel Level — FUEL LVL
• Fuel Rail Pressure — FRP
• Exhaust Gas Temperature — EGTS

The X300 also provides a multi-grid OBD data interface, allowing several supported parameters to be viewed on one screen.

Not every vehicle outputs every data item. Unsupported parameters may remain blank, unavailable, or display no valid reading.

Multiple OBD Display Modes

The X300 offers several ways to view vehicle information, allowing drivers to select the layout that best matches their needs.

Available interfaces shown in the product manual include:

• OBD triple-gauge mode
• Cruise display mode
• GPS mode
• 12-grid OBD data mode
• Audio spectrum display
• Inclinometer display
• G-force display

Users can swipe between supported screens and double tap designated display areas to change certain data items.

This provides greater flexibility than a basic single-screen OBD monitor.

GPS + BeiDou Positioning

The X300 supports GPS and BeiDou satellite positioning for GPS-based driving information.

The positioning system can provide:

• GPS-based vehicle speed
• Positioning status
• Driving information independent of certain OBD speed data
• Additional reference information during long-distance and off-road travel

GPS signal reception may be affected by tunnels, underground parking areas, tall buildings, dense trees, weather conditions, and the installation position of the device.

For better satellite reception, install the display in a position with a relatively clear view toward the windshield and sky.

Real-Time Engine Data Monitoring

Through the vehicle’s OBD-II interface, the X300 helps drivers view supported engine and operating data in real time.

Depending on vehicle compatibility, this may include:

• Engine RPM
• Engine load
• Intake air temperature
• Battery voltage
• Fuel level
• Fuel rail pressure
• Exhaust gas temperature
• Manifold absolute pressure

This information can help drivers better understand vehicle operating conditions during:

• Towing
• Long-distance travel
• Heavy-load driving
• Hill climbing
• Overlanding
• Off-road driving

The X300 is a monitoring display. It does not replace professional diagnostic equipment, scheduled maintenance, or inspection by a qualified technician.

Important Note About OBD-II Diagnostics

The X300 supports real-time OBD-II vehicle data monitoring.

Unless your confirmed product manual specifically states that the device can read and clear diagnostic trouble codes, avoid describing it as a full OBD fault-code scanner.

A more accurate description is:

Real-time OBD-II engine and vehicle data monitoring.

Only add the following claims if the device has confirmed support for them:

• Reading diagnostic trouble codes
• Clearing diagnostic trouble codes
• Resetting warning lights
• Displaying code definitions

Off-Road Inclinometer

The integrated inclinometer displays vehicle pitch and roll information, making the X300 useful for off-road vehicles, pickups, SUVs, and overlanding applications.

The inclinometer can help users view the vehicle’s orientation while driving or stopping on uneven terrain.

According to the operating instructions, users can perform horizontal calibration by pressing and holding the center of the inclinometer screen for approximately three seconds.

Recalibration may be needed after:

• Moving the display
• Changing the mounting angle
• Reinstalling the device
• Moving the device to another vehicle
• Parking on a confirmed level surface

The inclinometer provides reference angle information only. It does not replace safe driving practices, terrain assessment, vehicle stability systems, or driver judgment.

G-Force Meter

The X300 also includes a G-force display for monitoring directional force changes during acceleration, braking, and cornering.

The G-force interface provides an additional visual reference for:

• Acceleration
• Braking
• Turning
• Uneven terrain
• Dynamic vehicle movement

Displayed values are intended as driving reference information and should not be treated as certified performance or safety measurements.

Swipe and Tap Controls

The X300 uses an interactive screen interface for convenient operation.

Depending on the active page, users can:

• Swipe to move between display modes
• Double tap compatible display areas to change data items
• Press and hold the inclinometer screen to perform horizontal calibration
• Select different layouts for OBD, GPS, and off-road information

This allows the driver to customize the display according to the vehicle and driving situation.

Easy OBD-II Installation

The X300 connects to a compatible vehicle through the included OBD-II cable.

Basic installation steps:

1. Locate the vehicle’s OBD-II port.
2. Connect the X300 OBD-II cable.
3. Secure the display using the included mounting base.
4. Start the vehicle.
5. Allow the device to identify supported vehicle data.
6. Select the preferred display mode.
7. Confirm that the shown parameters are valid for the vehicle.

The OBD-II port is commonly located below the dashboard near the driver’s side, although its exact location varies by vehicle.

Vehicle Compatibility

The X300 is designed for supported OBD-II vehicles, including select:

• Toyota off-road models
• Mitsubishi off-road models
• Jeep Wrangler models
• Ford F-150 Raptor models
• Pickups
• SUVs
• Overlanding vehicles
• Other compatible OBD-II off-road vehicles

Compatibility should not be determined by brand name alone.

Before purchasing, confirm:

• Vehicle model
• Model year
• Fuel type
• OBD-II protocol
• Supported ECU data
• Available OBD-II PIDs
• Connector compatibility

Diesel, hybrid, electric, modified, imported, or region-specific vehicles may provide different data or have limited compatibility.
