Product Introduction
HUD short for Head Up Display, the main function is to reflect the car dashboard information (e.g. speed, RPM, water temperature, voltage, trip distance etc), and keep the driver eyes always on road to avoid the dangerous of lowering down head to read the instrument.
Product function:
- Light sensor: HUD can automatically adjust the brightness according to the environment
- Speed icon: OBD mode:speed Car ECU data,GPS mode:satellite data like compass
- System icon: short press the ‘+’ key within 5 seconds to choose OBD or GPS system
- Multi-function area: Speed, water temperature, voltage, mileage, driving time, fuel consumption, altitude, clock, 100 kilometers acceleration
- a + =100km acceleration, ASL=altitude, LHK=fuel consumption, MIN=travel time, TRIP=travel mileage
- Water temperature icon, Voltage icon
- Over-speed alarm icon
- Driving direction: Driving direction indication: W=West, N=North, S=South, E=East when the vehicle speed >5KM / H
- Speed display area
- Speed unit: KM/H=kilometer/hour, MPH=Mile/hour
- Satellite icon: flashing will stop until satellite numbers been got, please move the car to the open road, the GPS light will stay on if satellite signal been founded.
