Multifunctional trip computer - P20(Navigation)
Thank you for purchasing multifunctional trip computer produced by our company.This product
reads the driving data of cars through the OBD2 interface of car ECU, such as speed, RPM,fuel
consumption,water temperature and voltage etc,under the condition that the large field of vision
does not shift during the driving of the car. Instantly read the driving information to prevent the
driver from looking down at the instrument panel during transportation and affecting safety.This
product does not rewrite any data inside the ECU.

OBD2 FAQ:
1.No function is displayed,no power
Check whether the OBD cable is tight connection,pull down repeatedly to confirm,please try it on
another car if still not workable,analysis if it is an error from OBD diagnostic interface,if yes,please
repair it and connect the device again.

2.Only the car voltage displays and be automatic power off after 30 second
(1) This product is only available for OBDII and EOBD cars when it is in OBD2 mode
(2) This product OBD2 mode does not support OBD I and JOBD
(3) OBD2 is a car protocol(U.S.A Cars:2003 Other regions:2008)
(4) Switch to the GPS system using the USB cable to display, within 5 seconds of power short press
the ‘>’ key to select the GPS system.
3.The vehicle speed on HUD is not as same as speedometer’s
(1) Please check that the unit is correct KM/mile MPH, (speed unit switch please refer to the
settings)
(2) Vertical long press the ‘M’ button into the system settings, press ‘>’to select the speed
adjustment menu,and make a fine-tuning (e.g. meter displays 100 Km/h,device shows 105Km/h,use
default value 107-5=102 ).
4. There is an error on fuel consumption
(1) Checking your car displacement and make sure that the engine displacement of the device is as
same as your car’s(e.g. car is 2.0L,please set parameter value to 2.0L)
(2) if the displacement is the same, you can also do a fine-tuning settings(e.g. equipment fuel is
higher than 0.2L,please set the parameter to 98%) Recommended: fine-tuning is optional since it is
a real data from car computer
5.This device cannot auto shut down
After the car engine stops,the RPM on the machine can not be turned off,please set voltage to
13.2V or 13.6V,so that the car can be turn off after 3 minutes.
6. Automatic start-up will auto off when step the brake and same situation on Hybrid car in the
traffic.
(1) Setting to COM mode(in the menu of shutdown voltage)
(2) Setting shutdown delay to 300 seconds,so that it can turn off after 5 minutes
(3) Please switch to the GPS system(Short press ‘>’ within 5s)
7.Wrong operation lead to crashes
(1)Are there other other OBD devices on OBD2 interface (parking sensor,TPMS,lock lift
window,ELM27)
(2)Had your car been modified and brushed(central navigation,electronic throttle controller,fixed
speed cruise)
(3)No matter engine start stop,keyless entry or remote start will cause a crash,unplug other OBD
devices,and do a factory reset (see the menu settings)
Please switch to GPS system(short press ”>” within 5s) which should be connected with a USB.

GPS FAQ：
1.The screen is not displayed, no power
Check the OBD cable or car charger is in tight connections,try it several times to make sure,or plug a
USB cable into the cigarette lighter
2.No speed
GPS will take a short of time to search the satellites,please drive the car to the open road to get 5
and more satellites so that Gauge can be used normally
3.HUD cannot automatically power on or repeatedly extinguish during driving
(1) Please use the USB cable to insert the cigarette lighter
(2) If you use the OBD cable, change the sleep voltage to 13.0V or 12.8V
(3) If use the USB cable, make the sleep voltage off.
4.Inaccurate clock
Enter into the settings(System time):press‘>’to adjust and press‘M’ to save exit
5.Speed is not correct
(1) If the unit is correct,km KM/mile MPH, (speed unit switch reference settings item)
(2) The car factory had increased speed(5-7%)than real for drivers’ safety,satellite data is strictly
follow the international standards
(3) Fine-tuning the vehicle speed, e.g. meter display 100 Km/h, machine display 105Km/h,default
value 107-5=102
6.There is an error of travel direction
Satellite cannot recognize the driving direct without speed display,it will be normal until exceeds
5KM/H
7.Speed is still on display after the car stops
Satellite drift will be caused in underground parking,tunnel,overpass or blockers,please drive your
car on open road,then this situation can be solved after the satellite numbers >5
8.HUD cannot be automatically shut down after car stopped
(1) If connects by OBD cable, it will auto power off in 3 minutes.
(2) If it still not powers off in 5 minutes,please change the sleep voltage to 13.5V, or use the USB
cable.
Navigation FAQ ：
1. How to install APP
Scan QR code to download this APP(see manual)

2.How to use APP
(1) Please download this software
(2) manually turn on the Bluetooth and location
(3) click the icon of WiiYii,system will automatically search the Bluetooth and connect
2.Bluetooth cannot connect to Phone
(1) HUD host needs to display normally, if the OBD system cannot be connected, switch to GPS
system normal display
(2) Whether your phone's Bluetooth is connected to another device, delete the bluetooth device
that has been paired, and then bind to WYHUD
(3) Turn Bluetooth off again and then turn on your phone's Bluetooth, or restart your phone
(4) Make sure that other phones turn off Bluetooth
3.APP Bluetooth connection is not successful
(1)Check the phone system version and whether it supports Bluetooth 4.0, Apple system IOS9 or
above, Android 4.4 or above
(2)Need mobile phone to search for WYHUD via Bluetooth,Open traffic
(3)Turn on GPS navigation positioning, you can enter the navigation address after successful
positioning
4.App Bluetooth connection is successful,no display of input address
Please turn on the location service,open your network,check the signal,please move to a place
which has a strong signal,and enter the address again
5.HUD stuck during navigation or when you switch the display interface, speed
display is normal
Turn off the power-saving mode of the phone, turn off the screen forbidden function, or click to
enter the phone navigation page and stay on the phone navigation page
6.Navigate 10-20m from the indication point
Because the GPS positioning error is about 5-10 meters, it is normal for the satellite signal to be
10-20 meters when the signal is weak.
