Frequently Asked Questions
What is the difference between OBD2 mode and GPS mode?
OBD2 mode reads supported vehicle data directly from the diagnostic port, while GPS mode uses satellite positioning to display speed and travel information independently.
Will this work on every vehicle?
GPS mode is suitable for virtually all vehicles. OBD2 mode is designed for compatible gasoline vehicles that support OBD2 or EOBD protocols and may not function with many diesel vehicles, trucks, pickups, or electric vehicles.
Can I still use GPS functions while connected in OBD mode?
Yes. The updated system supports GPS-related information alongside compatible OBD functions.
Does it include overspeed and safety alerts?
Yes. The display supports overspeed warnings as well as other configurable alerts such as high coolant temperature, high RPM, low voltage, and fatigue driving reminders.
Is installation complicated?
No. The device is designed for quick plug-and-play installation and can typically be set up in just a few minutes on compatible vehicles.
Delivery was fast and the packaging was meticulous, making it easy to use.
Fast shipping, good packaging
Received well.
I just connected the power, and the quality is quite impressive.
It's a good product. The draft is also very good.
It was delivered, installed, and I've been using it for about 10 days now, and so far there seem to be no inconveniences. The setup is simple, Korean language is supported, making it easy to use, and it seems like a product that even beginners can easily use.
The product is very good. It is well-built and fits perfectly with the interior of the Peugeot 2008. The quality of the packaging is surprising.
It worked perfectly on my Onix, it marks everything at the same time, worth the price.
Excellent, does what it needs to do. Connected to a 2006 Citroen 1.0 petrol car, used to read the water level, which was missing in my car, and it does what it needs to do. There is also a mode to read errors and a GPS mode if you don't want to connect the device to the car's OBD2 port. Furthermore, the item arrived in perfect packaging condition.
fast delivery, excellent speedometer
It's very good for the price it has. Easy to install and with many screens and configurations.
The best I've ever bought, super fast delivery, display with excellent clarity, very easy to set up and accurate information, I recommend to everyone, great cost-benefit ratio.
