Product details
Product Description
The DUDUAUTO OBD-II Adapter is a smart plug-and-play diagnostic module designed to display real-time vehicle data directly on your car head unit, without the need for complicated setup or constant phone use.
Unlike traditional OBD devices, this adapter integrates with the OBD system protocol itself, allowing key driving information to appear straight on the head unit interface. Monitor vehicle speed, engine RPM, voltage, oil temperature, water temperature, fuel data, and more while driving.
Equipped with Bluetooth 5.1, the adapter delivers fast, stable data transmission with ultra-low power consumption. Its compact, discreet design allows it to remain plugged in without affecting cabin space or daily driving comfort.
The DUDUAUTO OBD-II Adapter supports 9 OBD protocols (V1.5) and works with most 12V petrol vehicles manufactured after 1996 (USA) and after 2003 (Europe). It also supports popular OBD apps such as Infocar, YMOBD, Torque Pro, and Car Scanner when additional data access is required.
