'Navigate to' page and 'SELECT LOCATION' window both have 'RECENTLY USED' tabs. I wonder how they operate: I assume they do not accumulate results of searches and navigations ad infinitum, yet I cannot see a means either to delete all or select individual items for deletion, which I should find useful.
Both Navigate to and Location selector save last 20 destinations/locations. If you want to use some navigation route repeatedly, best is to check "store permanently" in the Navigate to dialog.
