Peiying URZ0466 is an in-vehicle FM transmitter that provides Bluetooth audio streaming, direct playback from microSD, and dual USB ports for simultaneous charging and media playback. Designed for 12V and 24V systems, the compact black unit streams audio to a car radio over configurable FM frequencies and integrates a built-in microphone for hands-free voice calls. The device features an LED display and a voltage meter to monitor vehicle voltage while offering support for common audio formats.

Advantages

The transmitter supports Bluetooth 4.2 with a range up to 10 m and common audio/phone profiles (A2DP, AVRCP, HFP) for stable wireless playback and call handling. Two USB ports allow one port for music playback and charging and a second higher-current port for faster charging.

For calls, use the built-in microphone and standard call controls via the paired device or transmitter buttons.

Usage recommendations

Choose an FM frequency with minimal local radio interference for best audio quality and keep the device within Bluetooth range (up to 10 m) of the paired device. Use high-quality microSD cards (up to 64 GB) formatted according to your device’s instructions and avoid inserting/removing cards while playing. Monitor the integrated voltage meter to check vehicle power stability, and unplug the transmitter when the vehicle is not in use for extended periods.
