3. Setup and Installation

Installation of the VECHTEL car radio requires careful attention to wiring, especially for vehicles with fiber optic amplifier systems. It is recommended that installation be performed by a qualified professional.

3.1 Fiber Optic Canbus Connection

For vehicles equipped with an original fiber optic amplifier, a fiber optic Canbus decoder is required to ensure proper audio functionality. The decoder receives information from the original amplifier and connects it to the Android radio.

1. Locate the original fiber optic cable from your vehicle's amplifier.
2. Disconnect the original fiber optic cable.
3. Connect the fiber optic Canbus decoder to the disconnected original fiber optic cable.
4. Connect the RCA cables (red for right input, white for left input) from the decoder to the corresponding inputs on the Android radio.
5. Connect the power cables (ground and ACC +12V) from the decoder to the main power cable of the Android radio. This ensures the original amplifier and fiber optic Canbus function correctly.

Upon correct connection, the sound from the original amplifier will be routed through the new head unit. If sound is not immediately present, ensure all connections are secure and allow a few seconds for the system to initialize.

3.2 General Wiring

Connect the main power harness, GPS antenna, USB cables, and any other accessory cables (e.g., for backup camera, external microphone) as per the provided wiring diagram in the included user manual. Ensure all connections are secure to prevent intermittent issues.
