Nowhere on the box or in the pictures or on the little instruction sheet that I say what Bluetooth version it is. Only in the product description here on the page it mentions at one single time casually Bluetooth 5.3. well hopefully that's actually true. So far I haven't had to do anything to make it reconnect it's reconnected by itself every time. I do a lot of driving and my old one would not connect sometimes just enough to tic me off. My car with the key off all power goes down so I don't have to unplug it or anything like that. I would imagine most cards are like that.It's weird it doesn't mention anywhere in the instructions that holding the main volume button in well shut it off. That's what it does for me if you hold it in a couple seconds. It's nice to have that feature I wish my old one had that. But hopefully I don't have to really use it if it always connects reliably. Not have to unplug my old one a little bit and then plug it back in to repower for it to connect when it decides not to. That was the main reason for upgrading is my old one was Bluetooth 3.0 and it didn't always connect. So far it's doing what I was hoping for. It sounds good and I only hear a little bit of staticky noise when my car volume is literally maxed out. And just a little bit under max. Normal volume I don't even hear anything at all. It goes in snug in the cigarette lighter which is good. I wish I would have a button somewhere to change between blue, green and red led lights or something. That would be able to match most cars as my interior radio lights are a reddish orange. I tried the auxiliary and it worked although the supplied cable doesn't really snap into my phone hardly but it still worked. But it can come out easy so I found a spare that I have in a drawer and have that just in case I want to use it. I haven't tried SD card or the USB function yet. I suppose that would be the way to go to squeeze out the most quality you can with this. With auxiliary hooked up you lose volume knob control and ability to stop a YouTube video. Pressing it once will stop the sound for a YouTube video but not the video itself. It will stop a music player still. My old one did the same thing so I guess it's some kind of hardware compatibility thing going on with auxiliary. I use Bluetooth most of the time anyway and the stop start function works for YouTube videos and music players.So far I'm pretty happy with it and the sound quality is good and it's been reconnecting like a champ which is a big plus for me. Don't forget that if you hold the main volume knob in for a little bit it will shut off. I don't know why that feature is not mentioned anywhere. Holding it in again will turn it back on and it reconnected every time I've done that through just testing. Nice to see the car voltage at all times. Both chargers work just fine although using an app to test the 2.41 seem to always charge slightly faster than the QC 3.0. the most I've seen was 1.6 amps to my phone through the 2.4. and around 1.4 or so with the QC 3.0. Not sure what's going on there but they both work and have sufficient charge. I don't think my old one ever got the ratings it claimed either. You can use Ampere for basic or Accubattery for everything you would ever want to know with your phone battery condition and charging and discharging. This is on Android.

excellente

Se mete ruido en cualquier estación que escojas y la gente no te escucha bien cuando contestas el teléfono en la función de “manos libres“Además el vendedor hizo todo lo posible para que no pudiera devolverlo 🤦🏻Busca otra alternativa.

Prompt delivery.Did as instructions said.Programmed in on FM stereo.Worked first time.Sound quality good so far.Adjusted volume on both my mobile and the car until sound was not sounding strained.Brilliant.Can't fault in these early days.Would recommend.

Buena compra , cumple con lo que dice la caja

Si lo recomiendo, el plástico es de buena calidad

Buscaba un reproductor para el coche que no tiene usb, y no quería meter una caratula llamativa para que la roben, en mi caso el coche tiene entrada de audio minijack, con este reproductor se puede conectar por cable evitando al conducir cambiar de emisora, por emisora y bluetooth, tiene equalizador, puedes navegar por las carpetas del usb que conectes y elegir las canciones cómodamente, también se puede acelerar la canción hacia adelante y atrás

Al principio todo muy bien, después cuando ponía música con la USB, cambiaba de título de canción constantemente y ya no es posible usar esa función.

Es un producto que sincroniza de inmediato, el sonido es espectacular, no se desconecta y sus gráficos en pantalla le dan un toque muy elegante, sin fallas lo recomiendo.

TODO MUY BIEN FUNCIONA MUY BIEN Y RAPIDO DE INSTLAR Y USAR

El producto funciona muy bien, cumple con lo que dicen las especificaciones

Muy bonito y de buena calidad y cumple, es monoaural y no hay forma de modificarlo, todo es por medio del FM y la señal se convierte en monoaural, promete salida estéreo por salida auxiliar pero sólo admite entrada auxiliar, lo tuve que quitar por no ser estéreo

La mia esigenza era quella di poter ascoltare degli mp3 da pennetta (max 32Gb) tramite un'autoradio dotata solo di presa aux, e sono rimasto molto sorpreso dall'efficacia e la qualità del prodotto.Si infila facilmente nella presa accendisigari e rimane abbastanza stabile per poter essere comandato.L'accoppiamento bluetooth con il cellulare è molto rapido ed i tasti sono sufficientemente comodi ed intuitivi (a prova di noi boomer).L'unica noia è che il volume di uscita dalla presa aux è abbastanza basso. Nulla che non possa essere risolto con un aumento del volume dell'autoradio. Bisogna solo ricordarsene quando si ritorna su radio o CD.La qualità dell'audio è sufficiente, perfettamente adeguata all'impianto basico della mia vettura.Risulta ovvio che essendo le prese accendisigari posizionate molto in basso, ci si distrae alla guida e quindi consiglio di comandare il dispositivo solo a vettura ferma, tipo al semaforo.- Consiglio vivamente, inoltre, di verificare prima dell'acquisto, se nella posizione della presa accendisigari della propria vettura ci sia sufficiente spazio e che il dispositivo non interferisca con la leva del cambio.
