SmarTune-EXT broadcasts audio to your car stereo across the full FM band from 87.5MHz to 108.0MHz, so you can pick a clear frequency wherever you are driving. That is how a car without Bluetooth gets phone audio through its own speakers, using the radio it already has rather than a head unit replacement.

Pairing runs over Bluetooth 5.3 using an ATS2853 chipset, supporting the A2DP, AVRCP and HFP profiles across 2.402GHz to 2.480GHz with a 10m operating range. Those three profiles cover stereo audio, track control from the unit and hands-free calling, which is everything a car connection needs.

A microphone is built into the controller so calls come through the car speakers with your voice picked up from the unit rather than from a phone in a pocket. Placing the mic on the controller, within arm's reach on the dash or vent, is what keeps a caller's side of the conversation clear.

The USB-C port delivers 30W Power Delivery at 5V/3A, 9V/3A and 12V/2.5A, plus PPS from 3.3V to 11V at 3A. PPS lets a compatible phone draw exactly the voltage it wants, which keeps the handset cooler during a fast charge on a long drive.

A USB-A port adds Quick Charge 3.0 at 18W, running 5V/3A, 9V/2A or 12V/1.5A, bringing the combined output to 48W from a 12V to 24V socket. Two passengers can therefore fast-charge two different phones at once instead of taking turns on a single port.

The controller sits on a 1.5m cable and mounts to an AC vent or the dashboard, putting volume, track and call controls within reach instead of buried in the 12V socket. Its RGB lighting reacts to the music and surrounding sound, and the unit transmits at 20dBm or less.
