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

r/CarAV on Reddit: Bluetooth adapter for 12v and 3.5mm aux input?
March 14, 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.
