Can you understand how to use the satnav?

[Bob1954]

Would someone please run me through a simple instruction on the totally incomprehensible satnav system? All I want to do is enter a post code and save it with a name of the building I want to go to. So that I can go there tomorrow and in future. Thanks.

I have reached the 'store a favourites' page as shown below. I have altered the name I want to display. What do I do now?

The manual says 'select the right control button' if I do that I get a page that gives me three options 

Close speller

Clear entry field

Switch to Cyrillic characters.

Nothing about 'save favourite'

Whatever I do from here it either repeats itself or just crashes me back to the entry field.

Is there an error in the manual or is the program broken?
