Unfortunately, this does not work in this case. I have connected it to the AUX. Bluetooth would be the other option

Fits. Set the adapter to a free FM frequency and set the same frequency on the car radio. And off you go. Have fun

Hello, the DR 54 DAB+ can transmit the received signal to the car radio by means of wireless transmission via FM transmitter.
However, I have not tried this.
Greetings

You can set the FM transmitter on the DR 54 DAB+ to a frequency that you also set on the radio and then you can listen to the set station.
I do it the same way.
The disadvantage is that the display on the DR 54 DAB is a bit small.
