Simple fault elimination
Q: What to do when HUD can't be connected to the OBD connector?
Answer: Our product uses OBD II standard connector, so if it can't be connected to this connector, it shows that this kind of car doesn't sustain this kind of connector.
Q: What to do if it can't start up?
Answer: Please check that whether you have installed the OBD II connector correctly, and whether you have turned on the power supply.
Q: What to do if I can't detect the treaty?
Answer: Please turn on the HUD host machine while the engine is on, and ensure that the car is matched to the OBD II standard.
Q: What to do if the speed shows on the HUD is slower than that on the car instrument panel?
Answer: Almost all the instrument panels on the car can't show the right speed of the car, and 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.
Q: There is no prompt sound for alarm?
Answer: sound switch may be turned off. If the buzzer mark indicates turn on in the HUD, there will be sound, otherwise the switch is turned off.
