ELECTRONIC MAP

The Magellan 750NAV has an electronic map of the contiguous United States

and Canada stored on a hard drive. The map is divided into 10 separate regions

called Map Areas. Along with the purchase of the 750NAV one Map Area is

included (see Magellan Map Areas on page xx). Access to Map Areas is

controlled by Unlock Codes that are provided when the product is registered, or

when additional Map Areas are purchased or rented (see Unlock Features on

page xx).

TYPES OF COVERAGE

Detailed Coverage

Available in many metropolitan areas, this coverage provides complete

street and address level detail for the area. As well as, an extensive

Points of Interest database containing information about businesses,

banks, hotels, airports, restaurants, entertainment venues and many

other categories.

Inter-town Coverage

Available in less populated areas; this coverage level connects the Detailed

Coverage Areas with major roads shown on AAA



State maps. This type of

coverage also includes navigating to City Centers and Points of Interest.

Driving Across Map Areas

The Magellan 750NAV is currently not capable of routing outside of the chosen

Map Area. The system is can only route to a destination inside of each Map

Area.

Why the Map Database is divided into 10 Map Areas?

The contiguous United States and Canada have too much information to store all

of the data on a computer hard-drive. The average vehicle owner drives within a

hundred-mile radius from their home 99% of the time. To create a route with a

navigation system, the computer must perform numerous and complicated

calculations in a matter of seconds, virtually impossible if the computer had to

sort through the millions of bits of data that make up the U.S. and part of Canada.
