The horn buttons on my discovery have been very loose, occasionally falling out at "just the right time". ANy suggestions to keep them in place? Also, where can I get a new one as I just lost one out the window.

 

In this case your only choices are the dealer if you want a new one or a Rover salvage yard.

My right horn button did the same because one of the clips on the back broke. I ended up jerry rigging it with a little piece of metal and super glue. Now when I honk the things stay in place.
