Navigation intervention apparatus, intervention method and vehicle navigation system

An intervention method comprising:

• a request reception step of receiving acquisition requests from a plurality of input/output sections, said acquisition requests requesting various kinds of screens from a navigation processing section, each of said input/output sections including a display section;
• an intervention step of performing a mediating process or an adjusting process for said various kinds of screens in response to said acquisition requests, said various kinds of screens being received from said navigation processing section and being scheduled to be output to said plurality of input/output sections;
• and
• an output step of outputting to said plurality of input/output sections the various kinds of screens for which said intervention step performed the mediating process or the adjusting process.

A vehicle navigation system comprising:

• a navigation processing section for performing a navigation process;
• a plurality of input/output sections coupled to said navigation processing section, each of said input/output sections including a display section;
• and
• an intervention section intervening between said navigation processing section and said plurality of input/output sections, wherein said intervention section receives from said plurality of input/output sections acquisition requests requesting various kinds of screens from said navigation processing section, performs a mediating process or an adjusting process in response to said acquisition requests for said various kinds of screens which are received from said navigation processing section and are scheduled to be output to said plurality of input/output sections, and then outputs said various kinds of screens to said plurality of input/output sections.
