Unpaved Roads; Motorways; Ferries; U-Turns - Clarion MAP670 Owner's Manual

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, Clarion will use them but only as much as necessary. In this case a
warning icon will be shown on the Route Information screen (Page 39 ), 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.
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
(Page 77 ).
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.

5.4.4.5 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 authorised to enter.

5.4.4.6 Toll Roads

Toll roads are included in your routes by default. If you wish to travel more to avoid
paying a toll, disabling them will make Clarion plan the best toll-free route for you.
