reason, this will be displayed.
This can be mainly because something is wrong with the hardware. Something can be wrong
with the navigation system itself, serial interface (including poor serial connection), and GPS unit.
When no API response is returned from GPS unit, this will be displayed.
Following incidents can be causes for it.
• 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.)
