Abstract
Abstract An audio navigation system incorporating an audio CD player for playing an audio format CD constituting a data storage medium for the navigation system. The CD may store a database containing map data and navigation information, software including an algorithm for selecting a desired route between a designated starting point and destination, and speech data for generating audible spoken statements through a sound system. The audio CD player may be part of a sound system and may also play audio CDs carrying musical selections.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
108 words
In a navigation system which includes data storage means for storing a database containing map data and navigation information, means for storing software for controlling the system and effecting route selection in cooperation with the database, and a navigator processor connected to the means for storing software for operating the navigation system under control of the software, the improvement wherein said data storage means comprise: a) an audio CD player having a read head and means for positioning said read head in response to positioning signals from said navigator processor; and b) a CD storing the database in an audio format, said CD being playable by said player.
Claim 2
Dependent Claim
108 words
In a navigation system which includes data storage means for storing a database containing map data and navigation information, means for storing software for controlling the system and effecting route selection in cooperation with the database, and a navigator processor connected to the means for storing software for operating the navigation system under control of the software, the improvement wherein said data storage means comprise: a) an audio CD player having a read head and means for positioning said read head in response to positioning signals from said navigator processor; and b) a CD storing the database in an audio format, said CD being playable by said player.
Claim 3
Dependent Claim
47 words
