The LMM103 P6 car head up display adopts dual OBD2 and GPS signal acquisition technology, reducing data loss issues observed in single-signal display models. It is compatible with over 98% of OBD-compliant gasoline vehicles, making it a suitable option for auto parts retailers, modification workshops and auto repair service providers. With a 10Hz data refresh rate, the device displays real-time speed, RPM, coolant temperature, voltage, trip distance and clock readings on a color gradient LCD screen with auto-brightness adjustment. Four configurable safety alarms cover overspeed, high coolant temperature, low voltage and over-rev conditions. The plug-and-play OBD connector supports installation within 3 minutes without wire cutting, and the device operates within a temperature range of -20℃ to 70℃.
This OBD2 GPS HUD reads engine operation data through the vehicle’s OBD port, and supplements positioning-based speed data via a built-in GPS chip. For vehicles with incomplete OBD signal output, the GPS module provides stable speed data, reducing data loss defects associated with single-signal OBD-only dash gauges. The compatibility covers over 98% of OBD-compliant gasoline passenger vehicles.
The multifunctional vehicle HUD monitor simultaneously displays speed, 0-10000 RPM tachometer readings, coolant temperature, battery voltage, trip distance and clock. All data modules have passed 72-hour continuous signal stability tests, with a data refresh frequency of 10 times per second. This allows drivers to access full vehicle operation data without glancing at the original dashboard, supporting safe driving.
The auto OBD GPS speedometer is equipped with a color gradient HD LCD screen with an approximate 170° ultra-wide viewing angle, coated with anti-glare film to reduce reflection under strong sunlight. The automatic brightness adjustment system adapts to ambient light conditions for day and night driving. A built-in blue ambient light strip enhances interior aesthetic, with a backlight service life of 50,000 hours.
The LMM103 car head up display includes four configurable safety alarms: overspeed warning, high coolant temperature alert, low voltage prompt and over-revving reminder. Users can set alarm thresholds according to driving habits, with a dual reminder mode of buzzer and screen flash. This design helps reduce risks of engine damage and speeding violations during long-distance highway travel.
The universal OBD LCD dash gauge has a compact size of 13.5×10.5×8.5 cm and a net weight of 0.2184 kg, taking up minimal space on the center console. It connects directly via a standard OBD plug, requiring no wire cutting or circuit modification. A single installer can complete the full installation within 3 minutes, suitable for individual car owners and modification shops.
Each finished P6 OBD2 GPS HUD undergoes -20℃ to 70℃ alternating temperature cycle tests and continuous bump vibration tests before delivery. The device maintains stable performance against engine temperature fluctuations and rough road jolts, reducing failure rates such as screen flicker and signal disconnection during long-term vehicle use.

Daily urban commuting for private vehicles: Private car owners install the HUD on the center console to access real-time speed, voltage and coolant temperature data with overspeed alarms, helping control driving speed, reduce fuel costs and avoid speeding fines on urban roads. This scenario drives retail demand for auto parts stores.
Long-distance highway self-driving trips: Road trip users rely on the HUD for cross-city journeys. Dual OBD+GPS stable data output and high-temperature warning track engine working status throughout the trip, reminding drivers of mechanical abnormalities in advance.
Performance modified vehicle refitting: Car modification enthusiasts equip the speedometer on modified gasoline vehicles. Real-time RPM readings help them grasp engine rotation state during acceleration, adjust shifting timing properly and avoid over-rev damage to modified power assemblies.
Auto repair and parts retail: Repair garages and spare parts wholesalers stock the HUD as a universal aftermarket accessory. Its plug-and-play structure fits most OBD2 gasoline cars, supporting quick vehicle data detection and dashboard upgrade services for various customer vehicles.
