Real-Time OBD-II Vehicle Data

\n

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

\n

Depending on vehicle support, available data may include:

\n \n

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

\n

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

\n

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

\n \n \n

\n \n

GPS + BeiDou Positioning

\n

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

\n

The positioning system can provide:

\n \n

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

\n

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

\n

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

\n \n \n

\n \n

Real-Time Engine Data Monitoring

\n

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

\n

Depending on vehicle compatibility, this may include:

\n \n

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

\n

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

\n \n

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

\n

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

\n

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

\n

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.

\n

A more accurate description is:

\n \n

\n

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

\n

\n

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

\n \n

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

\n \n

\n \n

Off-Road Inclinometer

\n

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

\n

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

\n

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

\n

Recalibration may be needed after:

\n \n

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

\n

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

\n \n \n

\n \n

G-Force Meter

\n

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

\n

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

\n \n

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

\n

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