The manual provides a comprehensive troubleshooting guide for various symptoms, including sound issues, wiring errors, source selection problems, radio reception, incorrect character display, disc errors, playback order, and Bluetooth connectivity issues. Solutions range from adjusting volume and checking connections to resetting the unit, reattaching devices, and updating firmware or applications.
The manual provides detailed instructions for installation and wiring. It warns against using the unit with anything other than a 12V DC power supply, negative ground. The battery's negative terminal should be disconnected before wiring and mounting. Battery and Ignition wires should not be connected to the car chassis or Ground wire. Unconnected wires should be insulated. The unit must be grounded to the car's chassis after installation.
For safety, wiring and mounting should be done by professionals. The unit should be installed in the vehicle's console, and metal parts should not be touched during or shortly after use as they can become hot. Speaker wires should not be connected to the car chassis or Ground wire, or in parallel. Speakers with a maximum power of more than 50W should be used; if lower, the [AMP GAIN] setting should be changed to avoid damage. The unit should be mounted at an angle of less than 30°. If the vehicle wiring harness lacks an ignition terminal, the Ignition wire should be connected to the fuse box terminal that provides 12V DC power and is controlled by the ignition key. After installation, brake lamps, blinkers, and wipers should be checked. If a fuse blows, wires should be checked for contact with the car chassis before replacing the fuse.
The basic procedure involves removing the key, disconnecting the car battery, connecting wires (refer to wiring connection diagram), installing the unit (refer to in-dash mounting instructions), connecting the car battery, and resetting the unit.
The manual includes diagrams for in-dash mounting, showing how to attach and detach the unit, reset it, and replace the battery. It also details installation without the mounting sleeve, using specified screws. Instructions for removing the unit are also provided.
The wiring connection diagram illustrates connections for the signal cord, fuse (10A), remote wire, microphone input jack, antenna terminal, and factory wiring harness. It specifies connections for power antenna, amplifier, illumination, battery 12V, ignition 12V, ground, and front/rear speakers (left/right). It also includes information for connecting to a steering wheel remote control adapter.
The manual concludes with a part list for installation, including the faceplate, trim plate, mounting sleeve, wiring harness, and extraction key.
