What is the size of the plug-in connector, and which car models is it compatible with?

Sizes: Diameter 24mm with spring clip, Depth 57mm This size fits most car models but is unsuitable for sockets in recessed areas like glove boxes. After use, hold the car’s socket with one hand and pull out the charger with the other to avoid damage.

How can I avoid or reduce noise?

For best sound quality, set the car audio volume below 50% before connecting your phone. Then, connect to the FM frequency & Bluetooth. Adjust the phone & BC91 volume first. If it's still too low, adjust the car audio system to reach the ideal level.

How do I match & switch frequencies?

Turn on car radio to blank FM frequency. Set the BC91 to the same frequency as the car radio. Long-press the BC91 rotate button until frequency flashes. Turn clockwise to increase, counter-clockwise to decrease.

The device isn't working/power isn't responding/display isn't showing/car audio isn't receiving sound/unable to play?

1) Ensure that the FM transmitter is on. 2) Verify the transmission frequency of the FM transmitter matches the frequency of the car's radio. 3) Unplug the BC91 and connect it again. 4) Confirm the files on the USB device are supported by the BC91.

How to pair the FM transmitter with your phone via Bluetooth?

Plug BC91 into car cigarette lighter socket to power on. Enable your phone's Bluetooth is on. Then search for 'BC91 and select 'connect'. Once connected, you can start playing music, using navigation, or making hands-free calls.

Excellente qualité. Performant.

Très bien. Fait le job. Idéal sur voitures anciennes. Le bouton "Bass" rend le son plus rond, plus profond et la charge est vraiment rapide. La fonction "Transmetteur" est efficace : le bluetooth a fonctionné immédiatement sur 87.5. Très satisfait de mon achat. Une fonction appréciable : la petite molette avec le symbole téléphone tourne à gauche et à droite, ce qui permet de passer à la chanson suivante ou précédente sur Spotify.

Pushing through with

Il Trasmettitore Nulaxy 54W funziona correttamente e conformemente a quanto indicato garantendo di utilizzare il proprio telefono e la propria musica tramite la radio dell'auto che non dispone di Bluetooth Le intereferenze sono assenti tranne quando si passa in prossimità di ripetitori Le chiamate peccano di volume rispetto all'audio derivante da applicazioni di musica, ma è comunque fruibile I comandi sono semplici e intuitivi, e la scelta di colore RGB è un tocco di personalizzazione
