Switching on and off the device

Your Car Transmitter FM switches on automatically when you plug it into the car cigarette lighter. This will happen when the device is supplied with power. To turn it off, simply unplug the device from the cigarette lighter.

FM transmitter

Your Car Transmitter FM features a built-in FM transmitter to stream music from your source device to the car FM radio receiver. To ensure proper radio signal, tune into the very same radio frequency on both the transmitter and the receiver.

First of all, search for a free frequency on your car radio. You will identify a free frequency easily since the signal is weak or there is no signal at all when selecting it. Once you have selected a free frequency on your car radio, select the very same frequency on your Car Transmitter FM and press PLAY to start playback. At this point your car radio will receive the transmitted signal. If the quality is not good enough, fine-tune the frequency using the car radio or select another free frequency.

USB and microSD units

Play .mp3 and .wav files from your microSD cards and USB sticks (up to 128 GB). The contents play automatically a few seconds after inserting the microSD card or USB stick.

Press Next (3) or Back (2) to switch to the next or previous track.

The folders and files of your removable cards or sticks will be read in chronological order.
