Product Information
Product appearance & direction definition
System Composition
- The system mainly consists of 4 radars, with four radar brackets respectively at its front left, front right, rear left and rear right. Besides, there are other associated components, including audio (no-disc navigation/DVD), panel, exterior rearview mirrors, interior cords, and side-surrounding connecting plate.
- The four radars are identical in hardware and software. After installed, they will automatically adapt the direction through PIN11 and PIN12 address bit identification. When installed at high position, the hardware need earthing; when at low position, it doesn’t.
