Question: OBD car navigatioin charger can use on what car models?
Answer : All the cars that support the OBD standard can be used, the domestic production of all models after 2007 have
the OBD standard,so all can use the auto trip computer. Individual joint venture brands of vehicles (for example:
Volkswagen, GM, Honda, Toyota, etc.) has been applied before 2007, this need to be decided on the specific
models.
Question: where is the OBD Port in my car?
Answer : Find the OBD Connection in your car.It usually located under the steering wheel.above the brake pedal.Take the
driver as center in a round of Radius is 0.5m,Within driver’s hand reach.If you can’t find it,Please contact your l
ocal 4S dealer.(Different vehicles has different OBD interface position, but they are the same shape, refer to pic
showed below)
Question: what should be paid attention to when install & uninstall the OBD car navigation charger ?
Answer : Installation:(Right install&uninstall steps are used where equipment might be damaged if care is not taken)may
damage the device)

Question: Why it works fin in my car but can’t work on the other cars,how to do “factory settings”?
Answer :To ensure the quick use.The OBD car navigation charger scan all the communication mode and lock to matching
mode for the first time use to make it is 100%suitable for this car. If the trip computer used on other cars,need to
do initialization before using .And the trip computer will rescan the communication mode automatically.
The step for initialization:Press the reset hole for 10 seconds with navigation stylus till the light on OBD shine
again
Question: Why Smart Trip-computer display slower speed than the car dashboard display speed?
Answer : Almost all of the instruments in the car speed do not display accurate, it is out of the security considerations,
the car factory design on 2-5% higher than the actual speed, that is why when the dashboard shows the speed
is140Km/H on the highway, and no over speed shooting, because actually the real speed is about 120 Km/H.
Question: Why does the speed getting slower, one hundred kilometers instant fuel consumption is growing?
Answer : When Car in neutral gear, the oil is not off and the engine is in fuel injection situation and combustion, fuel
consumption is not 0.100Km instant fuel consumption = (100 * Cumulative injection quantity) / (speed * time).
This time the engine fuel injection less and speed is slower, so driving 100Km need more time, when the
speed is very slow, the time is almost infinite. According to the formula, this time the 100 km instant fuel
consumption should be increasing.
Question: How to set the water temperature alarm function?
Answer : Run "Smart Trip-computer" software, after working properly, click "Set" → click on "Page Up" or "Page Down"
to the "Alarm settings" → Click "Coolant alarm". Enter the alarm value, you can normally use. Note: the smart
trip computer water temperature alarm default setting is 100℃, the water temperature set value is different for
different models. The car has a low-speed, high-speed electronic fan, temperature is reached dangerous range,
high-speed electronic fan open, effectively reduce the temperature of the coolant, if the fan is faulty at this time,
it would be dangerous. It is recommended that check the temperature on the fan of their own car and set the
temperature value as alarm value.
Question: How to set up real-time fuel consumption when it is not accurate?
Answer : You need to set the fuel consumption calibration run "Smart Trip-computer" software, after working properly,
click the "Set" → click on "Page Up" or "Page Down" to " fuel consumption Settings" → click "Fuel Consumption".
Specific operation samples as bellows.
Question: When speed is 2000RPM, sliding with gear, the real-time fuel consumption is about 10(Liter/100Km), is it a wrong
calculation? Why in neutral gear sliding instant fuel consumption is jumped, if neutral gear output more power?
Answer : Idling sliding fuel consumption slightly higher than not sliding. about 1(Liter/Hour),because if power steering
at this time, electrical, brake pump must consume power. If the speed is not high in gear sliding. the instant
fuel consumption is really great, if sliding with gear of 1500RPM or more , generally ECU will slow down
off the oil, the instantaneous fuel consumption is actually zero.
Question: When sliding with gear with 800 RPM, instand fuel consumption 0, why my fuel consumption is 7-8?
Answer : Actually whether deceleration and off the oil also depends on the speed and water temperature,
If it is 7-8 means did not slow down at not off the oil, you can try sliding with gear at 60 Km/h, the fuel
consumption should be displayed under 3.
Question: In what situation, the software need to be reinstall and auto trip computer back to normal
Answer : If the auto trip computer system is not working alright and is recommended to reinstall the software.
