1.The difference between C3 and C3 Plus
C3 ： OBD + GPS---dual systems
C3 Plus ：OBD + GPS+Navigation---dual systems and navigation（Navigation function:driving direction, time, distance,speed）
Navigation FAQ ：
1. How to install APP
(1) Please download software ‘WiiYii’
(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.
OBD2 FAQ:
1.No function is displayed,no power
Check whether the OBD cableis 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:2007)
(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.
If the OBD system does not work properly, try to switch the GPS system,use USB cable plug into the cigarette lighter.
