Product description

MANUAL SPEED CORRECTION

Adjustable Speed If you find that the speed does not match the speed of your car’s meter, you can adjust it as follows: Step 1 Confirm that your speed unit is MPH, if not, please enter the setting mode 9 to switch(refer to the user manual for the method of entering the setting menu), ensure that the speed unit is MPH, then you could follow step 2. Step 2 Speed fine-tuning: Enter setup mode 1, you will see the initial value is 107, assuming that your meter value is 100 mph, and the HUD is 105 mph, that is, the HUD is 5mph faster than the meter value, then you need to subtract 5mph from the initial value 107, which means that you need to adjust the initial value to 102. So the secret of the adjustment is to add/subtract the difference between the meter and the HUD using the initial value 107. We can also provide you with adjustment suggestions; Step 3 If the speed of the instrument and HUD cannot be matched by the above two steps, we suggest that you enter the setting mode 14, restore the factory Settings, and then measure the speed again or repeat the above two steps for adjustment; Step 4 If you encounter any problems in the adjustment process or think that the HUD does not meet your expectations, please do not worry, we will provide you with more careful after-sales service.
