Nav System- how do I delete location marks?

Yes, and it's not at ALL intuitive. I keep having to fumble around a bit to remember the exact sequence.

Basically, you have to go to Menu->Setup to get into the NAV setup pages. As you'll see, there are multiple screens that you go through. Somewhere on the second or third page is a Locations (I think that's the name) item with a Delete button. Press Delete and it brings up a scrollable list of all your previous destinations. You can selectively delete or delete the entire list.

I think Ray's talking about Memory Points, not previous destinations. I keep hitting the Mark button by accident too

You want to press "MENU", then "Memory", then the "Delete" button next to "Memory points". Then select each one you want to delete, or go nuts and press "Delete All".

 

Most "marks" are destination icons, I deleted them one by one (total 54), some are for previous visited locations, I deleted them either.
