Three steps to your first song.
Complete setup while parked. Your phone connects to the FMVC2; the FMVC2 sends the sound to your car stereo.
Plug in and power up.
Insert the FMVC2 into a powered vehicle cigarette-lighter / accessory socket. The manual supports 12–24V input. Adjust the flexible neck so the display is easy to see without blocking your view.
Pair your phone.
Open your phone’s Bluetooth settings and connect to the FMVC2. A blinking blue light indicates pairing readiness; steady blue indicates a connection.
Choose FM or AUX.
Match the transmitter and car radio to the same unused FM frequency, or connect the supplied 3.5mm AUX cable to your stereo’s AUX input. Then start audio on your phone.
One connection.
Two ways to listen.
Bluetooth brings audio from your phone to the FMVC2. Choose the output your car stereo supports.
Through your FM radio.
Find a quiet, unused frequency on the car radio. Use the FMVC2 frequency-tuning controls to select the same frequency, then leave the radio tuned there.
The supported range is 87.5–108 MHz. If you hear interference, choose another unused frequency on both devices while parked.
Through an AUX input.
Connect the supplied 3.5mm cable from the FMVC2 AUX jack to your car stereo’s AUX input. Select AUX as the stereo source and keep the phone connected to the FMVC2 over Bluetooth.
Your stereo needs a compatible AUX input. This route carries audio over the cable instead of the FM broadcast.
Connected, but silent?
Check the complete path: Bluetooth connection, the stereo source, matching FM frequency or AUX cable, and volume on your phone and stereo. Test with audio already playing on the phone.
Know your everyday controls.
The hands-free button handles music and calls. The separate voice-assistant button activates the assistant on your phone. Refer to the manual’s button diagrams for physical locations and frequency-tuning controls.

Track selection
Use the Previous / Next controls to move through tracks. In frequency-tuning mode, these controls adjust the frequency.
Phone voice assistant
Press the voice-assistant button once to activate Siri / Google Assistant on a compatible phone, and again to deactivate it.
Say it. Keep listening.
The FMVC2 supports these eight built-in English phrases for offline control:
The built-in phrases work without mobile data. They are separate from your phone’s Siri / Google Assistant, whose services may require internet access.
Get the sound back.
Start with power, Bluetooth and your stereo’s selected audio source.
Ask Rexing support →Why can I hear static or a radio station?
Choose an unused FM frequency and set both the FMVC2 and car radio to exactly the same frequency. A local station may become stronger as you travel; retune when parked. If your stereo has an AUX input, try the supplied AUX cable instead.
My phone is connected, but there is no sound.
Check both parts of the audio path: your phone must connect to the FMVC2 over Bluetooth, and your stereo must receive the FMVC2 through matching FM frequencies or its AUX input. Start audio on the phone and check the phone and stereo volume.
Does the FMVC2 record video or need a memory card?
No. FMVC2 is a Bluetooth FM transmitter and hands-free car kit. Camera recording, memory-card formatting and dash-cam playback instructions do not apply to this model.
Do the voice commands need mobile data?
The eight built-in control phrases work offline. Streaming music and services used by Siri or Google Assistant may still need an internet connection on your phone.
What does the flashing light mean?
Blinking blue means the unit is ready to pair. Steady blue indicates a Bluetooth connection. Alternating blue and green indicates that the phone voice assistant has been activated and is listening.
Can I charge two devices at once?
Yes. The unit has two USB charging ports: one rated 5V/2.4A and one supporting QC3.0. Actual charging speed depends on the connected device and cable; use the port that matches your device.
What if the unit does not power on?
Check that the vehicle accessory socket is powered and the unit is firmly seated. The guide lists 12–24V input. If power is still absent, contact support. Do not disassemble the unit; fuse replacement must match the type and rating specified in the manual.
Is the battery-voltage display a battery charger?
No. The unit displays vehicle voltage at startup and includes a low-battery alert. Its USB ports charge connected devices; they do not recharge the vehicle battery.
