Looking for some help here!

I have a Fiat Punto 75 ELX model on a N plate, My horn has suddenly stopped working and my stereo controls on the steering wheel have also stopped working. I have changed the fuse which the owner books says is the one, still not working.....

Any ideas?

Sounds like the connection to your steering loom has become disconnected. I only have a horn so I am afriad I do not know where this is.
