1. Introduction
The Pinmany RZ-WC51 CAN Bus Decoder is designed to integrate your vehicle's CAN Bus data with an aftermarket Android head unit. This device acts as a data converter, allowing your Android head unit to communicate with the car's systems, enabling features such as steering wheel controls, door status, and other vehicle-specific information to be displayed or controlled through the head unit. It is specifically compatible with the VGV U70 2020 model and various Android head units (7, 8, 9, 10 inches).

4. Installation Guide
4.1. Step 1: Connection of Cable Adapter
- Identify the 16-pin CAN plug on your vehicle's wiring harness.
- Connect this 16-pin CAN plug into the corresponding 16-pin socket of the RZ-WC51 CAN Bus Decoder.
4.2. Step 2: Pin Definition
Ensure correct wiring by referring to the pin definitions for the 16-pin connector:
| Pin No. | Definition |
|---|---|
| 1 | GND |
| 2 | BATT |
| 3 | CAN-H |
| 4 | CAN-L |
| 5 | NC |
| 6 | NC |
| 7 | PARK-OUT/NC |
| 8 | NC |
| 9 | NC |
| 10 | NC |
| 11 | NC |
| 12 | CAM-PWR (+5V) |
| 13 | UART-RX |
| 14 | NC |
| 15 | SWC |
| 16 | UART-TX |
4.3. Step 3: Set up CAN Bus on Android Head Unit
The exact setup method may vary between different Android head units. The following steps demonstrate a common procedure. Please consult your head unit's vendor manual if these steps differ significantly.
- Enter Settings: On your Android head unit, navigate to the main settings menu. Look for an icon or option related to 'Car Settings' or 'System Settings'.
- Enter Factory Settings: Within the settings, locate and enter 'Factory Settings'. You may be prompted for a password. Common factory passwords include: 3368, 1617, 8317, 8888. If none of these work, consult your Android radio vendor.
- Enter CAN Bus Settings: Once in factory settings, find the 'CAN Bus Settings' or 'Car Type Settings' option.
- Select Manufacturer and Model:
- Select the CAN Bus Box manufacturer, which is 'Raise'.
- Select the correct car model and year, 'VGV U70 2020'.
- Save and Reboot: After selecting the correct options, save the settings and reboot your Android head unit for the changes to take effect.
5. Operating Instructions
Once the RZ-WC51 CAN Bus Decoder is correctly installed and configured with your Android head unit, it operates passively in the background. It continuously translates CAN Bus signals from your VGV U70 2020 into a format your Android head unit can understand. This enables various car functions to be integrated with your head unit, such as:
- Steering wheel control functionality.
- Display of vehicle information (e.g., door status, climate control).
- Automatic camera switching (e.g., reverse camera activation).
No direct user interaction with the decoder is typically required after initial setup. All interactions will be through your Android head unit's interface.
6. Maintenance
The RZ-WC51 CAN Bus Decoder is a low-maintenance device. To ensure its longevity and proper function:
- Keep the device dry and away from moisture.
- Avoid exposing the device to extreme temperatures.
- Do not attempt to open the casing, as this may void any potential warranty and could damage internal components.
- Clean the exterior gently with a dry, soft cloth if necessary. Avoid using harsh chemicals or abrasive materials.
7. Troubleshooting
- Device Not Functioning:
- Check all wiring connections carefully against the pin definition chart (Figure 6). Improper wiring is a common cause of malfunction.
- Ensure the operating voltage supplied to the decoder is within the +9V to +16V range.
- Verify that your Android head unit has an 8-pin connector and supports serial communication.
- CAN Bus Features Not Working on Head Unit:
- Revisit the CAN Bus setup steps on your Android head unit (Section 4.3). Ensure the correct manufacturer ('Raise') and car model ('VGV U70 2020') are selected.
- If you cannot access factory settings due to an unknown password, consult your Android radio vendor for assistance.
- Ensure the Android head unit is compatible with the CAN Bus decoder.
- Physical Damage: If the decoder shows signs of physical damage, discontinue use and contact support.
8. User Tips
- Double-Check Compatibility: Always confirm that both your vehicle model and your Android head unit are compatible with the RZ-WC51 decoder before attempting installation.
- Organize Wiring: Use cable ties or electrical tape to neatly secure all wiring connections. This prevents accidental disconnections and ensures a clean installation.
- Test Thoroughly: After installation and configuration, test all integrated functions (steering wheel controls, door sensors, etc.) to ensure they are working as expected.
