What it does

This Scosche FM transmitter connects any device with a 3.5mm audio jack to a car radio via the FM band. It is powered by a built-in 300mAh rechargeable battery that provides up to 10 hours of continuous playback. The unit includes a digital display and simple buttons for frequency adjustment. It suits drivers who want wireless audio from older phones, MP3 players, or tablets without replacing the head unit.

FM band limits

The transmitter operates on the standard FM broadcast band and relies on finding an unused local frequency. Signal stability depends on PLL phase-locking technology and last-frequency memory, but strong local stations or interference can disrupt audio quality. The effective range is approximately 15 meters. Users must manually scan for a clear channel in each new area, as the optimal frequency varies by region and no automatic scanning feature is present.

Install and common issues

Setup requires plugging the 3.5mm cable into the source device, tuning the car radio to a blank FM frequency, and matching the transmitter to that same channel. The package includes a charging cable and user manual. A frequent issue is that the hands-free calling function uses the connected phone's microphone, not the transmitter itself. Selecting a frequency that conflicts with a strong local station causes static or bleed-over, so testing several channels is necessary.

Questions about this item

Should I pick the 300mAh battery version or look for a higher capacity?

This model ships with a 300mAh rechargeable battery rated for 10 hours of continuous playback. No alternative capacity is offered for this MPN.

What does the 15-metre launch distance mean when I am driving?

It indicates the transmitter can reach your car radio from up to 15 metres away, so placement anywhere in the cabin gives a reliable FM signal.

How does the 3.5mm input work with my car stereo?

Plug the 3.5mm connector into your phone or player, tune the transmitter and your car radio to the same blank FM frequency, and audio plays through the speakers.
