<Error details>
• Timeout occurs just because something is wrong with serial interface (poor contact), or data
gets garbled and looks like another response.
• When a response different from the requested API is returned because of malfunction of
GPS unit and another request for API is already requested, the time-out response to the first
request is determined to be incorrect one.
• Navigation system performs so slow that it cannot handle the response within the time limit
even though a response is returned from GPS unit, or GPS unit cannot handle the same kind
of situation within the time limit. (The time limit is 1.5 sec.)
• Others
• After confirming the connection, GPS unit is reset before routine communication is started.
• Connection is only confirmed when serial contact is poor.
