PURPOSE:To obviate inputting an object position at every usage occasion after turning-off an engine and also to facilitate a usage operation by providing a nonvolatile memory for a object position, etc., and holding collectively inputted plural object positions even in case of power source loss. CONSTITUTION:The plural object positions are set in a memory 5 for the object position, etc. An object destination coordinate is stored for the respective object positions. Here, a setting flag=1 is raised for respective kinds of object position data and it is judged whether or not the setting of the plural object positions are completed. In this case, the object destination coordinate is stored in the nonvolatile memory so that it is held even when the engine is turned off and the power source of the memory is lost and when the engine is turned on the operation for newly storing the object destination coordinate becomes unnecessary. That is, a prescribed route is retrieved concerning the object position of the setting flag=1. A driver can select what the object positions are guided by screen display and search for the route. |
