Unverified Area Routing
When driving to your destination, you
have the choice of using or not using
"unverified" roads. You make this
choice in Set up screen (second). The
next few pages contain an example of a
route to a destination in an unverified
area explaining the routing differences
found in unverified areas.
With Unverified Area Routing Off,
the system tries to use verified roads
whenever possible. In this example,
since only verified streets are used, it
created a longer route than necessary.
With Unverified Area Routing On,
the route is shorter, but consists of
unverified (light colored) streets that
may not be accurate. Because the streets
are unverified, there may be errors in
street location, name, or address range.
Additional caution is recommended in
these areas. Always obey posted traffic
Because both routes bypass or use
unverified streets, an initial Disclaimer
screen is provided. It is recommended
that you stop and review the map.

Unverified roads are shown only when
viewing the map in the 1/20, 1/8, and
1/4 mile map scales, or the 80, 200,
and 400 meter map scales.
