What this device does

The Scosche KM18 Plus is a Bluetooth 5.4 FM transmitter that adds hands-free calling and music streaming to any 12 V or 24 V vehicle. A 1.44 inch LCD shows caller ID, frequency and battery voltage while a flexible gooseneck positions the screen for easy viewing. Dual fast-charge ports deliver 30 W PD and 18 W QC 3.0 simultaneously.

Check your vehicle first

Confirm the cabin has a standard 12 V or 24 V power socket to supply the unit. Verify the factory stereo can receive FM signals and offers either a 3.5 mm auxiliary input or an unused FM frequency for transmission. Ensure a TF card or paired smartphone is available as an audio source before installation.

What the extras provide

A 3.5 mm auxiliary cable is included for a direct wired link when FM reception is weak. The TF card slot enables music playback without a phone connected. Bluetooth 5.4 reduces drop-outs during calls and streaming. The adjustable gooseneck lets the driver set the screen angle once and leave it fixed.

Questions about this item

Does the KM18 Plus include a 3.5 mm AUX cable or must I buy one separately?

A 3.5 mm female-to-male auxiliary cable is supplied in the box so no separate purchase is needed.

Should I use the 30 W Type-C PD port or the 18 W USB QC3.0 port for fastest phone charging?

Use the Type-C PD 30 W port for devices that support Power Delivery; the USB QC3.0 18 W port is best for Quick Charge compatible phones.

What does the 48 W total rating mean when both ports are used at once?

The 48 W figure is the combined maximum output — 30 W from the Type-C PD port plus 18 W from the USB QC3.0 port when charging two devices simultaneously.
