Car Head Up Display HUD OBD2 Speedometer Windshield Project

HUD short for Head Up Display.It displays driving datas on the front windshield such as speed, rpm, fuel consumption,water temperature,voltage;avoiding drivers become dangerous because of watching the instrument while driving.Drivers can read the driving information instantly,and can always keep the best state on the way with HUD.

HUD Main Functions&Features:

1.Available for cars with OBD2 and EUOBD port(Car automatic diagnosis system) ,plug and play

2. Screen 5.5 inch HD display

3.Multi-color design makes the screen more abundant and easier to read

4. Nano-technology to eliminate double reflections,more clear.

5. New function: Driving distance measurement

6.Rich Contents: speed, RPM, water temperature, voltage, instantaneous fuel consumption,average fuel consumption,driving distance measurement, voltage, shift reminders,fatigue driving reminders,low voltage alarm,high water temperature alarm,over speed alarm, engine failure alarm, eliminate the fault code,freely switch between kilometers&miles.

7. Auto power on/off: HUD start and off with vehicle started and shutdown, effective protection of the car battery;retaining the manual switch mode,more easy to control HUD.

8. Automatic and manual brightness adjustment mode,driving without glare

Troubleshooting

1.The screen without any display, and no power

Start the car engine; check if the OBD cable line is tight; please pull out the OBD cable more times to ensure; check if HUD power switch turns on. If still no display, please change another car to test, analyze whether the car OBD diagnostic interface is good, if it is not good, please repair it and try again.

2.When HUD power on, HUD only shows the car voltage and be automatic power off after a few seconds driving.

OBD mode only available for cars with OBD2 and EU-OBD agreement(European region: after 2003 years, Other region: after 2007 years)

HUD Products don’t support JOBD and OBDI protocol.

3.The device is stuck or stuck during driving

Check the OBD interface if connected with other OBD device,please remove other OBD devices and do the factory reset (find menu 16).

4.Inaccurate Speed  

(1)First check speed unit is correct or not, the speed unit including KM/H or MPH (refer to menu 11)

(2) When HUD is power on, vertical press the setting button for 5 seconds to enter into the menu 1 and the parameter shows 107,push left or right the setting button to increase or decrease the value according to the difference until it shows correct one. After adjustment, vertical press in 5 seconds to save it.(Example:If the dashboard shows 100,and HUD shows 103,then change the HUD default value from 107 to 104)

5.Inaccurate fuel consumption

The unit for fuel consumption is L/100KM, HUD display is the single driving fuel consumption, while car display is Integrated average driving fuel consumption, so it is normal if there are difference.

HUD display three kinds of fuel consumption

a. Idle mode: HUD display Instantaneous fuel consumption per hour (L/H), it means HUD can figure out how much oil the car will consumed after start engine in one hour

b. Driving mode: HUD display Instantaneous fuel consumption of 100KM

c. Finish driving: HUD display is average fuel consumption of 100KM, when turn off the car, HUD will auto turn off in 10s

6.Stop-star cars,HUD shutdown after braking

Vertical press in 5 seconds to enter into menu setting, short press 14 times to menu 14, the default parameter is 20, push left or right to change to 180, then power off time will be 3 minutes,then vertical press in 5 seconds to save and exit,HUD will power off in 3 minutes.

7.HUD can not auto power off(RPM or Speed not at 0)

When HUD is power on,long press in the button for 5 seconds to enter into menu,set to menu 13. Change the voltage from 0 to 13.2V or 13.5V. Once the adjustment finished,long press in the setting button for 5 seconds to save and exit.

8.When HUD turn off, but restart

Find menu 13, adjust the default to 13.6-13.8 V

9.Clock calibration (this device doesn’t have battery,it needs to calibrate the clock once power off )

Long press in the button for 5 seconds to enter into the menu,short press in the button 15 times,to menu 15,it displays 12:00 and flash,pull left to switch the hour and minute,pull right to adjust the digital number,once finished ,long press in the button for 5 seconds to save and exit.
