Make your car or truck completely Bluetooth capable with the Wireless FM Transmitter and Charger from Car and Driver. Just plug the compact unit into your 12V cigarette lighter socket and set your radio and the FMX121 to the same station. Now you're ready to enjoy streaming music, and hands-free calls through your car stereo. Plus, you can charge up to two devices, like smartphones and tablets, simultaneously. As many U.S. states have instituted hands-free driving regulations, it is vital for any driver to have access to wireless calling, navigation, and streaming services that are essentially hands-free. FMX121 upgrades your car, truck, SUV, sedan to the latest Bluetooth technology so you can travel with confidence. With USB and USB-C ports, the FM Transmitter allows you to charge your electronic devices directly from the car's DC power outlet. Use FMX121 with your favorite Voice Activated Assistant for the complete hands-free experience. The FM Transmitter will automatically pair with the last successfully connected media device the next time it is turned on. Power input: DC 12-24V. Power output: Type C/USB Port: 5V/2.4A. Supports SD memory cards up to 64 Gigabytes.
