4. Installation Guide
This section outlines the steps for installing your new Roinvou car stereo. Ensure your vehicle is turned off and the negative battery terminal is disconnected before proceeding.
4.1. Removing the Original Head Unit
- Prepare Tools: Use a plastic removal tool to prevent scratching your dashboard.
- Remove Faceplate: Gently pry around the edges of the original radio's faceplate to release the clips. Work your way around until the entire faceplate is loose.
- Remove Vents: If your new head unit requires a different faceplate, carefully remove the air vents from the original faceplate by lifting the clips. These vents will be transferred to the new trim.
- Unscrew Head Unit: Locate and remove the four screws securing the original head unit in place (two on each side).
- Disconnect Wiring: Carefully pull the original head unit out slightly and disconnect all wiring harnesses and the antenna cable from the back. There are typically four main connections: the main power/speaker harness, two smaller harnesses, and the antenna.
4.2. Wiring the New Head Unit
Your Roinvou car stereo comes with a dedicated wiring harness designed for direct plug-and-play installation in compatible Subaru models. This eliminates the need for cutting or soldering factory wires.
- Connect Main Harness: Connect the provided main wiring harness from the Roinvou unit to your vehicle's factory harness. Ensure a secure connection.
- Connect Power Amplifier: If your vehicle has a stock power amplifier, connect the original AMP control cable to the ACC wire on the provided power cable.
- GPS Antenna: Connect the GPS antenna to the designated port on the back of the head unit. Route the antenna cable to a location on your dashboard with a clear view of the sky for optimal signal reception.
- Radio Antenna: Connect the vehicle's radio antenna to the new head unit.
- USB Cables: Connect the dual USB cables to the back of the unit and route them to a convenient location, such as the glove compartment or center console, for connecting USB devices.
- External Microphone: Connect the external microphone for improved call quality and voice commands. Route it to a suitable location, such as near the rearview mirror or on the A-pillar.
4.3. Steering Wheel Control (SWC) Connection
The unit supports steering wheel controls for convenience.
- Without CANBUS Decoder: Connect the plugs or the steering wheel control wires (Key1/Key2) in the power cable to the corresponding port or wire of your original car. Then, manually match the buttons in the unit's settings to activate the function.
- With CANBUS Decoder: Connect the CANBUS decoder before powering on the machine. Go to Settings > Factory Settings (Password 8888) > Protocol settings. Select the brand of the CANBUS decoder and the matching model and year to enable SWC.
4.4. Backup Camera Connection
The unit supports a backup camera for enhanced safety.
- Connect Rear Camera Input Cable: Plug the rear camera input cable into the designated port on the head unit. This cable must be plugged in even if a reverse camera is not being used, as it can affect Bluetooth and WiFi signal reception.
- Connect Camera: Connect the AHD backup camera to the rear camera input cable. Ensure the camera's power wire is connected to the reversing lamp and the ground wire to a suitable ground point.
4.5. Final Installation
- Test Connections: Before fully securing the unit, reconnect the negative battery terminal and briefly power on the unit to ensure all connections are working correctly (audio, display, touch response, etc.).
- Secure Head Unit: Carefully slide the new head unit into the dashboard opening and secure it with the screws removed earlier.
- Install Faceplate: Snap the new trim panel (with transferred vents) into place around the head unit.
