When a road type is selected, its lamp is green, if not, it turns red and is crossed-out
as already described in Page 12.
Note: Excluding a route is a preference. It does not necessarily mean total
prohibition. If your destination can only be accessed using some of the excluded
road types, This GPS device will use them but only as much as necessary. In this
case a warning icon will be shown on the Route Information screen, and the road not
matching your preference will be displayed in alternate color on the map.
4.4.4.1 Unpaved Roads
Unpaved roads are excluded by default, as they can be in a bad condition and you
usually cannot reach the speed limit on them.
4.4.4.2 Highways
When driving a slow car or towing another vehicle, you may prefer not to take
motorways.
4.4.4.3 Ferries
The accessibility of temporary ferries is not necessarily included in the map data.
Furthermore you may need to pay fare, so you may consider disabling them from the
preset enabled status.
4.4.4.4 U-turns
Although displayed amongst road types, this is a type of action. Most drivers prefer
to replace them with a few normal left and/or right turns in the next few junctions, so
it is disabled by default.
Turning back on dual carriageways is not considered as a u-turn.
Note: If you are not totally against u-turns, leave them on here, and add a certain
penalty (equivalent extra distance to travel) in Advanced settings Route options.
Note: Via points are handled as stopovers with regards to u-turns. It means disabling
u-turns on this page will avoid u-turns during the entire route if possible, but when
reaching a via point, the following part of the route may be planned starting in the
opposite direction.
4.4.4.5 Permit needed
To use some roads or enter some areas you may need special permit or permission
from the owners. These roads are excluded from your routes by default. Use this
switch if your vehicle is authorized to enter.
