5.4.4 Road types to include/exclude
To let the route fit your needs you can also set which road types are to be considered
for or to be excluded from the route if possible. When a road type is selected, its lamp
is green, if not, it turns red and is crossed-out as already described in Page 11.
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, Uniden Navigation will use them but only as much as necessary. In this case a
warning icon will be shown on the Route Information screen (Page 38), and the road
not matching your preference will be displayed in alternate colour on the map.
5.4.4.1 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.
5.4.4.2 Motorways
When driving a slow car or towing another vehicle, you may prefer not to take motorways.
5.4.4.3 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.
5.4.4.4 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.
