Setup Guide

Follow these steps to set up your RIWUSI Bluetooth Car Adapter and connect it to your vehicle's audio system.

Step 1: Find a Blank FM Channel
Insert the RIWUSI Bluetooth Car Adapter into your car's cigarette lighter socket. Turn on your car radio and find an empty FM frequency (a channel with static or no broadcast). This frequency will be used to transmit audio from the adapter to your car's speakers.

Step 2: Tune the Adapter to the Car Channel
Adjust the FM frequency on the RIWUSI adapter to match the blank FM channel you found on your car radio. Use the control knob or dedicated buttons on the adapter to change the frequency. The adapter's LED display will show the current frequency.

Once connected, the adapter's LED display may indicate a successful Bluetooth connection. You can now play audio from your device through your car's speakers.

Troubleshooting

If you encounter issues with your RIWUSI Bluetooth Car Adapter, please refer to the following common problems and solutions:

Problem	Possible Cause / Solution
No power / Adapter not turning on.	Ensure the adapter is fully inserted into the car's cigarette lighter socket. Check if the car's cigarette lighter socket is receiving power (e.g., by testing with another device). Verify the car's fuse for the cigarette lighter socket is not blown.
Cannot connect via Bluetooth.	Make sure Bluetooth is enabled on your mobile device. Ensure the adapter is in pairing mode (usually indicated by a flashing Bluetooth icon or LED). Forget "BC47" from your device's Bluetooth history and try pairing again. Move your mobile device closer to the adapter.
Poor audio quality / Static or interference.	Ensure the FM frequency on the adapter exactly matches a clear, blank frequency on your car radio. Try a different blank FM frequency if the current one has interference. Adjust the volume on both your mobile device and car radio. Ensure no other strong FM signals are nearby.
Charging is slow or not working.	Verify that your charging cable is not damaged and is compatible with fast charging standards (PD/QC). Ensure your device supports PD or QC fast charging for optimal speeds. Try using a different charging port or cable.
Adapter loses connection in socket.	Ensure the adapter is firmly seated in the cigarette lighter socket. If the socket is loose, consider using the adapter in a different vehicle or consulting a car technician.
