Today i’m in a Daf 460, the radio is on mute i’ve tried putting it back to factory settings & still hee haw out of it, i’m now hoarse singing to myself any ideas ■■
Press the mute button again.
Are you sure it’s on mute and not on “rearaux” . If it’s “rearaux” try pressing the bottom lefthand button or top left I can’t remember but it’s one of them.
“rearaux” is what you select if you want to play an mp3 player through the system. My night driver hasn’t worked out how to turn it off, I’ll tell him one day 
if it is a euro 6 model pull out the fuse for the phone and replace it after 10 seconds
or stop, turn the ignition off for 10 seconds then on again then turn the radio back on
its
I’m having same problem,there’s a 5amp fuse in fuse box marked with a picture of a phone pull it out and it will reset itself.ive to go to daf on Friday they tell me there’s a software update to stop this happening…
