4. Function Introduction
4.1 CAN Bus Signal Decoding
Mainly realized by the CAN Bus decoder. The decoder has a built-in high-performance decoding chip, which can quickly adapt to the original vehicle's CAN Bus protocol and accurately parse various core data transmitted by the original vehicle's CAN Bus, including car key switch (ACC), reverse gear, small lights, steering wheel buttons, on-board computer data, door switch status, air conditioning operation parameters, etc. It converts the parsed signal into a format recognizable by the Android head unit to ensure that the Android head unit can read and display it normally, and ensure the synchronous presentation of the original vehicle information.
4.2 Steering Wheel Button Adaptation
This function decodes the original vehicle's steering wheel button commands, supporting common operations such as volume adjustment and song switching. It can be used directly after adaptation, and some models may require additional setting of learning-type buttons.
4.3 Original Vehicle Function Compatibility
This product realizes two-way signal transmission between the Android head unit and the original vehicle system. After installation, it will not affect the original vehicle functions such as air conditioning control, light adjustment, and fault feedback, ensuring the normal use of the vehicle.
4.4 No Damage to Original Vehicle Wiring Harness, Plug and Play
No manual wiring or cutting of the original vehicle wiring harness is required. It can be directly docked through a dedicated connector, which accurately matches the original vehicle cable connector and the Android head unit connector. The installation is simple and efficient. Note: Due to differences in vehicle brand, model, and year, please be sure to select the corresponding vehicle model through the CAN Bus setting after installation to ensure that the decoder matches the original vehicle protocol; if the corresponding vehicle model is not found or functional adaptation abnormalities occur, please contact the manufacturer for an adaptation plan.
