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.
