This product is designed for vehicles with a 12V or 5V DC negative ground electrical system. Do not use on other voltage systems. 2. This adapter is compatible only with OEM or aftermarket car stereos equipped with a CD changer port. Compatibility may vary depending on vehicle brand or stereo model. 3. Ensure the car stereo is powered off before installation to prevent damage. Professional installation at a car dealer or audio specialist is recommended. 4. In most cases, the car stereo must be removed to connect the Bluetooth kit to the CD changer port on the radio module. For certain models, installation may be possible in the glove box or trunk where an external CD changer port is accessible. 5. Review the car stereo wiring diagram (typically located on the top of the stereo unit) before installation. Identify the following ports on the back of the stereo: CD changer port, B+/Ub+/12V ACC port (may be labeled as BAT, Bup+, B-U, MEM +12, KL.30), and GND port. How to Install: 1. Turn off the engine and remove the key from the ignition. If the car radio requires a security code, ensure you have it before disconnecting the unit. 2. Remove the radio from the dashboard to access the rear connections and locate the CD changer port. Refer to the vehicle or stereo manual, or consult a professional for removal instructions. 3. Pre-connect the wire harness to the car stereo module. Ensure a secure connection, then attach the harness connector to the CD changer port on the back of the stereo. 4. For certain models, connect the red wire to the B+/Ub+/12V ACC port (or labeled equivalent such as BAT, Bup+, B-U, MEM +12, KL.30) or a compatible 5V/12V power source. Connect the black wire to the GND terminal on the head unit’s power module. 5. Start the vehicle and turn on the car stereo. Press the CD, Disc, Mode, CDC, SOURCE, or AUX button one or two times to switch to music playback mode. 6. Enable Bluetooth on your mobile device, search for the device named “JieRi BT5608”, and complete pairing. Once connected, test audio playback to confirm proper function. 7. After successful testing, reinstall the stereo, route and secure the wire harness and module box in a suitable location (such as the glove box or storage compartment), fasten the screws between the module and harness, and return the head unit to its original position. Installation is now complete.
