|Hud Common Problems Solutions|
1.HUD do not display ,Without electricity
Reason:Start the car engine, and check if the OBD cable is connected tightly or not,try several times,check whether HUD master switch is on.If HUD still not display ,please try another car,analyze whether the car OBD interface is broken.If the broken OBD interface,suggest that fix OBD interface first and then connect HUD again,HUD should work .
2.With electricity on,but only show car voltage,and auto-off after 30 seconds.
Reason:HUD work only for OBDII and EOBD interface.
Car model year (US Cars after 2003 years,other region Cars after 2007 years,only these cars start using OBDII or EOBD),HUD don’t work for OBDI and JOBD.So pls change a OBD2 car to use
3.After the car is turned off, HUD do not automatically turn off for a long time.
Reason: The default is 13.2V that HUD automatic turn off ,automotive voltage higher than 13.2 volts, HUD automatic turn on and automotive voltage lower than 13.2 volts, hud automatic turn off. HUD do not turn off , then long press vertically the wave button for 5 seconds to Menu, short press vertically 7 times, the menu display 7, and up or down the wave button to adjust the voltage parameter to 135 or more little higher.Do not be too high, preventing the car voltage can not reach the starting voltage of HUD.
4.Read not clearly under sunlight , has double image.
Solution:Check HUD body whether the protect film has been torn or not ,and then stick the reflection film on the front windowshield.
5.Wrong operation lead to crashes.
Solution: Restore factory settings,(check detail on user manual)
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.
Solution:Switch on HUD and keep charging.long press vertically the wave button for 5 seconds to Menu, short press vertically to menu 0, the default value is 107, and up or down the wave button to increase or decrease the value, and make the HUD show the same speed as dashboard,long press the wave button vertically to save and exist.
7.Over Speed Alarm
Solution:Default over speed is 120,if you wanna adjust bigger or smaller
Switch on HUD,long press vertically the wave button for 5 seconds to Menu, short press vertically to menu 6,default Parameter Value is 120,this mean HUD will alarm when your speed up to 120,then you could up or down the wave button to increase or decrease the value, After finish adjustment,exist by long press vertically wave button for 5 seconds.
8.How to restore factory settings
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 .
