Abstract
An on-board navigation apparatus which uses a driver having a changer function to selectively reproduce any of music- and map-containing storage media. When it becomes necessary to read map data during reproduction of a music-containing medium, the current medium is replaced with the applicable map-containing medium upon arrival of an intra-music interval. This allows one driver driving both music and map data media to read map data without interrupting the piece of music being reproduced.
