Smart Car Locator

The Werleo Bluetooth FM transmitter plugs into a 12 or 24 volt cigarette lighter socket and automatically saves the vehicle position to the Fast Find Car app on iOS or Android. It suits drivers who want a simple way to locate their parked car and stream audio through the factory stereo. Buyers needing a built-in GPS logger or a dedicated tracking subscription will not find those features here.

FM Transmitter Behaviour

Audio streams wirelessly over the 87.5 to 108.0 MHz band and the supplier notes clearer sound when tuned between 106.0 and 108.0 MHz. Playback also works from a USB stick or micro SD card loaded with MP3 files. The single 5 volt 2.1 amp port charges a phone while the transmitter runs. Users who require multiple simultaneous charging ports or higher output for tablets will need a separate charger.

FM Band Limits

The analogue FM interface covers the full 87.5 to 108.0 MHz range but remains subject to local station interference and signal drift in dense urban areas. Audio quality depends on finding a clear frequency and cannot match a direct auxiliary or digital connection. Buyers who want lossless playback or a stable link regardless of radio congestion should consider a wired or Bluetooth-to-aux adapter instead.

Questions about this item

Does the Werleo transmitter draw much power or generate heat when left plugged in all day?

It runs on the vehicle 12 V or 24 V system and supplies only 2.1 A at 5 V through the USB port, so power draw and heat stay very low during continuous use.

What must my car already have for this device to work?

A working cigarette-lighter socket providing 12 V or 24 V and an FM radio that can tune between 87.5 and 108.0 MHz.

Will the FM transmitter interfere with an older car stereo that only receives analog signals?

No — the unit broadcasts on standard FM frequencies from 87.5 to 108.0 MHz, so any analog tuner can pick up the audio just like a regular station.
