My 2021 T6.1 Media unit has totally failed, no music, phone connection, navigation, reversing camera screen etc, just a completely dead black screen. I have researched the fuse and come up with fuse number 53 but that appears intact. Even more annoyingly, I am away on holiday at the moment so unable to get to my dealer. Can anyone confirm this is the correct fuse or have any other ideas or experience of this issue.
