When To Use The Highway/Motorway Map - Pharos Ostia 3.x User Manual

6.8 When to use the Highway/Motorway Map

The Highway/Motorway map is to be used in conjunction with the
standard street-level maps to assist in routing from one map to
another, so that the fewest maps are opened at once. This single
Highway map contains only the Highways/Motorways for the
specified Country, but no street-level information.
If the Highway/Motorway map is loaded to the mobile device or
Storage Card, Ostia will automatically open it when required. In
addition, Ostia will also open the map for the Destination if it is not
already opened.
When Ostia automatically opens the Highway/Motorway and the
Destination maps, it will clear out any POR previously set on the
map. After Ostia opens the Highway/Motorway and the Destination
maps, the Origin will have to be re-entered manually unless you
have a GPS Lock.
Note: If the Route calculation method for "No Highway/Motorways" is
used, and you are on a Highway/Motorway, Ostia will not be able to
calculate the Route until you are no longer on the Highway/Motorway
The Canadian Highway/Motorway Map contains
highway/motorway information for all metropolitan areas, but some
additional areas are not covered by this map. If you are unable to
create a route using the Highway/Motorway map, please make
sure you manually open all the local maps needed for the route in
order to make the calculation.
