FAQ for Car Head Up Display Vehicle-Mounted HUD
Following are some questions frequently asked by customers.
FAQ:
Q1. What to do when HUD can't be connected to the OBD connector?
A1: Our product adopts OBD II standard connector. If it can't be connected to this connector, it shows that your vehicle is not compatible with this kind of connector.
Q2: What to do if it can't start up?
A2: Please check whether you have installed the OBD II connector correctly, and whether you have turned on the power supply.
Q3: What to do if I can't detect the treaty?
A3: Please turn on the HUD host machine while the engine is on, and ensure that the vehicle is matched to the OBD II standard.
Q4: What to do if the speed showed on the HUD is lower than that on the vehicle instrument panel?
A4: Almost all the instrument panels on the vehicle can't show the right speed of the vehicle, and the speed on it is often 2-5％ higher than the real speed, which is mainly out of the consideration of safety. This can explain why people often don't get photographed when they drive at a speed as high as 140 KM/H. In fact, the real speed is only 120 KM/H.
Q5: What to do if there is no reminding sound for alarm?
A5: Sound switch may be turned off. If the buzzer mark is displayed on the HUD, it means that the sound is on, otherwise the switch is turned off.
