You can rename them and specify their locations. To determine the location you can
use the same Find menu options as for a route destination, and depending on that
choice and the information available, the location will be shown here as a street
address, a latitude/longitude position, or both.
Note: If you tap either of your favourite destinations in the Find menu before defining
it, Navsure will offer to take you to this screen to set it up.
4.1.3 Automatic Night Colours
Using the automatic night mode, Navsure will change between the daylight and night
colour schemes a few minutes before sunrise and a few minutes after sunset based
on the time and location information provided by your GPS. Once you set a
permanent colour scheme in the Quick menu (Page 58), this automatic mode turns
off. If you need Navsure to switch between colours for you again, you need to reenable
this feature.
4.1.4 Route Recalculation
Once a route is planned, this setting will tell Navsure what to do when you deviate
from that route.
4.1.4.1 Automatic
The route will be recalculated automatically a few seconds after you go astray.
4.1.4.2 Ask First
Navsure can also ask your preference each time you leave the planned route. The
route will not be recalculated until you make your choice from the menu that
automatically appears .
