Horn and Radio issues

Hi all. New to forum. Lots of great info available. My 2006 Jetta tdi has lost power to the radio and the horn doesn't work. From what I'veread, these two issues don't seem to be related but trying to read the fuse box(s) schematics is like Latin. No habla. Anybody having similar issues? Love the car. It's a hand-me-down from my wife. We bought her a 2016 Jetta. Thanx in advance for any wisdom imparted.

BTW, these issues did not occur at same time. Thanks for all the responses
