How to clear NAV1?

Greetings from Spain!
This may sound a bit silly, but I can't seem to find a way to clear NAV1 so there is no active bearing or course indications on the screen. How can I just clear the current selected NAV1? I read the manual twice
but can't find anything there.
Thanks in advance,
Richard
