I use a generic 12v to USB, and a Tunai Firefly. It supports LDAC Bluetooth and honestly sounds better than the USB-C to aux adapter on my phone. Answer from Deleted User on reddit.com

November 7, 2025 - Again this is powered by the 12V socket, with dedicated buttons for tuning the FM frequency, and an adjustable arm to better position the screen to the driver's preferences. Sumind's transmitter is a little more complex than Lencent's, thanks to all the different buttons and microSD support. Personally, switching back between the card and Bluetooth ...

r/CarAV on Reddit: Bluetooth adapter for 12v and 3.5mm aux input?
March 11, 2023 -
I feel like this is simple, but I'm struggling. I'm trying to find a bluetooth adapter that plugs into a 12v socket with a pigtail for the aux input and streams via Bluetooth.
There's a ton of fm transmitters that pull power from 12v socket. A ton of plug straight into 3.5mm and power separate. But nothing that you plug into the 12v socket with a short aux cable to the aux port. What do I search?
Paired with bluetooth audio degradation and fm degradation they sound like crap.
