Introduction

The main function is to display the car dashboard information(e.g.speed, driving direction, local time, driving distance, driving time ),and keep the driver’s eyes always on road to avoid the dangerous of lowering down head to read the dashboard.

Kindly Attention:

OBD2 mode working voltage: 11V~18VDC (12vdc/200ma), when voltage is higher than 24v, please use a USB cable for GPS mode

System Choice:

This product is a dual system (OBD2+GPS): push left the wave button to choose OBD2 or GPS system, if you have no operation, after 5 seconds, HUD will automatically enter into the OBD2 system.For second use, when HUD start, if don’t push the wave button, after 5 seconds, HUD will automatically enter into the system the last time chosen.

OBD System： available for cars with OBD2 interface （Only OBD line can be used）GPS System： universal for cars ,buses ,trucks （Both OBD line and USB line can be used ）

Data Stream

Show all the vehicle data stream

Error code set

Scan DTCs: scan the ECU to check if there is the error code ,and show the error detailsClean DTCs: switch to Clean the DTCs, short press in the button to finish the cleaning

DTC Trouble Code Search

OBD-II search powered by dot.report

Please note:

It is recommended to unplug the OBD device if your car doesn’t been used for more than one week. Due to the OBD equipment for long power, standby current is about 20ma ,in theory, the use time of a common battery is 1 month, surely, situation of each car is different.

OBD2 System Troubleshooting:

The screen without any display ,and no powerStart the car engine ;check if the OBD cable line is tight ;please pull down the OBD cables more times to ensure ;check if product 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.
Only shows the car voltage and be automatic power off after 60 second when the device is with power This product just available for cars with OBD2 agreement and EU-OBD agreement(European region: after 03 years, Other region: after 07 years) This Products don not support JOBD and OBDI and recommended test for another car.
Inaccurate Speeda. First check the speed unit is correct or not, the speed unit including KM/H and MPH ,please refer to the setting to switch the unit.b. When the product is power on ,long press in the button to enter into the menu option, and right push once switch to setting then short press in the button to the menu, and right push the button switch to the speed adjust option.(if the dashboard shows 100,and the device shows the 101,change the default value at 106%)
Inaccurate Fuel consumptionCheck your car displacement, and set the device same as your car(if your car is 2.0L,then change the device value at 2.0L).The fuel consumption can be adjusted,but we don’t suggest to change it ,because all the datas are read from the car ECU directly.
