Solution:Switch on HUD,upside turn the wave button for 5s, you will hear a tick of HUD and led all display,it shows HUD has finish the restore to factory setting.
Q 1:Why HUD display vehicle speed would smaller than dashboard ?
A 1:Consider the safety of drivers,the car factory made some process on speed.Usually dashboard speed will faster 2-6 yards than HUD display.In this time,you could make a adjustment on set up menu 0 until HUD display speed are same with dashboard.This is why the reason some cars on 120 on highway but the camera do not show they over speed.
Q 2:Could HUD auto-on or off ? Could HUD turn on or off by manual?
A 2:Yes,HUD could auto-on or off.Usually HUD auto-off after shut down cars for 30 seconds.HUD auto-on after start engine for 5 seconds. HUD with power switch itself,so HUD could turn on or off by manual.We suggest that you could turn off HUD by manual if you don’t drive for a long time.
Q3:How to enter set up
A 3:Plug OBD cable -> Press switch and release after 5 seconds --> showing big 107 and small 0 (888 and 88 will show, other place is black) -->big 107 means set-up parameter, small 0 means the zero menu—press the big number to 117,small number to 1—press the big number to 100,small number to 2—recycling press to choose the parameter.
HUD default menu and its corresponding parameter:
0-(107) 1-(117) 2-(25) 3-(120) 4-(0) 5-(1) 6-(1) 7-(132)
Q 4:Explain about Parameter Value of Speed and Rotation Speed
A 4:HUD default speed is 107,it’s represent 107%;HUD works by reading sensor data from the vehicle interior ECU computer, while car dashboard generally direct access to sensor data, dashboard information display by simulation,it would allow to exist some difference.Referring to the difference,date from ECU,multiplied by 107%,then you check HUD display,they are basically the same.
If you adjust speed to 100,HUD will display same date with ECU,but different from dashboard.
Similarly,Rotation speed are same .
