Cheers Hadrian, honestly, thank you I was/am hoping we've missed a trick somewhere. But yep, been through all the menus, absolutely all the sound that is associated with the Sony stereo isn't working. Radio, CD, USB, reverse noise, navigation and mobile phone. Absolutely nothing. I've pulled each and every fuse from both the fuse box under the bonnet and the fuse box behind the glove box. I've had the complete stereo out, absolutely every last bit of the stereo.
The car is now sat with the battery disconnected, hoping for a hard reset.
Someone please help.
