1. A guide system for a vehicle comprising:
- guide data storage means for storing guide data for guidance objects located along roads to be travelled and the vicinity thereof;
present position detecting a means for detecting present position;
guide data output means including first search means for searching for guidance objects within a first range determined relative to said detected present position, second search means for searching for guidance objects within a second range determined relative to said detected present position, said second range being different from said first range, and read means for reading out of said guide data storage means guide data for a guidance object located by either of said first and second search means;
a manual key for issuing an instruction for a search operation by said second search means, said first search means being operative to execute its search absent said instruction; and

Abstract
A guide system for a vehicle includes guide data storage containing guide data for conversion into output information concerning guidance objects along roads to be travelled by the vehicle and in the general area thereof. A TV monitor and microphone serve to output the information. A present position detector detects the present position which is traced on a map display output on the TV monitor. A first search routine searches over a first area range for guidance objects on the basis of the detected present position and a second search routine searches for guidance objects over a second area range different from the first area range. Once a guidance object is located, the guide data for that located guidance object is read out from the guide data storage and converted into output information. A manual key is provided on a remote controller for switching to the second search routine.
