My radio is not working at...it just write silence on dashboard...what could be the problem?

The radio beeps when the radio is turned on how can you get it to stop

L'autoradio non riesce a sintonizzare molte stazioni radio o pare che il segnale sia molto basso e non lo riceve bene. Ho provato anche ad installare un amplificatore sull'antenna, ma il risultato non cambia di molto.

When i want to listen to music on a pendrive or via bluetooth, the stereo changes the source and puts it on radio. When i change it again to BT i can listen to the song for like 20 seconds and it goes again to radio. Any idea ?

Pas d alimentation électrique du tableau de bord, du dégivrage de la vitre arrière, pas d'autoradio.

When drving faults appear on my radio and a warning triangle on my dash board it will say brake light faulty, or indicator faulty but they work fine also says I have an abs fault that now constantly stays on my dash that I don’t think I have.
