WHAT's the Difference Between GPS and OBDII?
1. GPS works for all vehicles, but it doesn't show as much data as OBDII.
2.OBDII has more powerful features and data,but is only suitable for vehicles produced after 2008.

Speed Data Display Error:
Because the system is designed to warn drivers not to overspeed.Therefore,the HUD's default display speed is 5-10 km/h higher than the actual driving speed of the car.
You can adjust the data to be synchronized when using. For example,the meter displays 100 KM/H.The device displays 105 KM/H.Set the default value from 107 to 102.After saving the settings,there is no need to adjust again in the future.

ATTENTION:
1.Please tear off the protective film before using this product, otherwise it will affect the clarity of the projection.
2.Because the car's glass is double glazed,the device will have slight ghosting, but it will not affect the use. If the reflective film (contained in the package) is used,the slight ghosting will not occur.
3.Shutdown voltage setting:Adjust to 13.2V or higher when it cannot be turned off.
