Hello @Bobbywir,

The important thing here is what type of connection is used with your car audio receiver.

As you said, Bluetooth cannot transport HiFi quality audio, there is a compression which provides at best AAC 256 kbps audio quality.

As long as you are connected via an audio or data cable (jack to jack, jack to Lightning, USB to Lightning), there is no additional audio compression so you can fully enjoy HiFi quality playback.

If you’re planning to use a receiver with wireless CarPlay built-in, a local Wi-Fi connection is established between the receiver and your iPhone (Bluetooth is used only during the setup phase). With a good Wi-Fi signal, the bandwidth is high enough to transmit the audio using ALAC (Apple equivalent for FLAC) as it is done on AirPlay. In this case you will also get HiFi quality audio.

We have HiFi available in all devices, however, your device has to be compatible with HiFi quality.

I just received my new BMW car. I have tested Deezer HiFi with Harman Kardon and the sound is wonderfull. But just if I connect the phone via USB cable, with wireless CarPlay the sound is not the same, bad in my opinion. I am just asking is someone else has experienced the same, and I need just to wait for IOS update or else. I have Iphone 11 with IOS14.
The old car had cabled Carplay, much better for sound perfomance. :(

Hello @boscam, thanks for the feedback. Have you checked your audio quality settings in the Deezer App? I moved your message here so you can have a look at @GuillaumeDZ’s answer.

Hello Kevin, yes everything is set to hi fidelity. The sound is less rich. Via USB I can feel more dynamic.
