Basemap Routing Vs. Detailed Map Routing - Magellan RoadMate 300 Reference Manual

The Magellan RoadMate comes with a built-in basemap. The basemap
contains highways and city centers. The basemap does not contain street
address information, points of interest, or other map data (such as waterways,
railroads, or parks). The Magellan RoadMate can route via the basemap to a
city center or point selected on the screen using the available road data. Where
there is no data, a thin, straight line from point to point will be used with a flag
indicating the start and finish of normal street routing. You will be routed from
your current position via a straight line to the nearest major road or freeway on-
ramp, along the freeway to the off-ramp closest to your destination, and then
via straight line to your destination.
With the detailed map, you are routed using turn-by-turn guidance on all city
streets and highways. Also, you have access to detailed map data and points of
interest. As you can see, with the detailed map the route becomes more direct
using the surface streets.
With this information in mind, let's see how the Magellan RoadMate routes
between regions.
