2.5 No Response From Remote Control
No Response From Remote Control
Introduction
The remote control sends signals to the processor assembly in either of two methods. In the first method, with the remote
control removed from the remote control cradle and pointed at the display assembly, the signal is received by the display
assembly, then transmitted through the display wiring harness to the processor assembly. In this case the power to
transmit the signal is from the remote control batteries.
The second method is with the remote control situated in the remote control cradle. In this case, signals from the remote
control transmit directly through the remote control cradle and its wiring harness to the processor assembly. The power

2.8 Guidance Problems
The processor continuously calculates the vehicle position. When a destination is entered, the processor calculates the
best possible route depending on the user's preferences. If the user does not follow the directions provided by the
processor, the processor must recalculate another route, then provide the user with new directions. Problems may occur
in guidance when the user does not follow the processor route instructions and makes a number of changes in directions
before the processor can recalculate the route. The processor eventually calculates the correct route, but must be given
some time. In this case, the user has obviously strayed from processor guidance instructions; the processor always
maintains the correct location of the vehicle.

3.4 Read GPS Data
Ser v ice personnel commonly suspect bad s atellite reception as the cause of poor navigation system performance. GPS
data supplied to the processor is processed every few seconds to confirm the position calculated by the map-matching
software is correct. Good GPS data is essential to the system when it is first installed in the vehicle or when the vehicle is
moved from one location to another without the navigation system being active.
Within the navigation proc essor unit, there is a separate GPS receiver which receives GPS data from the antenna and
transmits calculated data to the processor. If the internal GPS receiver is faulty, the navigation processor must be
replaced.
Receiver State Description Comment
3D Position 3D data on the location of the vehicle is
available when the system receives data
from four or more satellites.
In this condition, the satellite icon on the guidance
screen is GREEN. This is the normal condition.
2D Position 2D data on the location of the vehicle is
available when the system receives data
from three or more satellites.
No geographic heig ht can be determ ined in this
mode. Positional accuracy is reduced.
The satellite icon on the guidance screen is RED.
This is not the normal conditi o n, but indic ates poor
or reduced reception.
Tracking Data from one satellite has been received by
the system. This condition is normally encountered when the
system is first powered up. The GPS receiver is in
this mode for up to 10 minutes depending upon
reception conditions.
The satellite icon on the guidance screen is RED.
Search SAT The system has a valid almanac and is
searching for satellites. This condition is normally encountered when the
system is first powered up. The GPS receiver is in
this mode for up to 10 minutes depending upon
reception conditions.
The satellite icon on the guidance screen is RED.
REC Error The system does not receive satellite signals. This condition usually occurs if the GPS antenna is
not connected or the cable is damaged. If the GPS
antenna and cable are serviceable, the GPS
receiver is faulty and should b e replace d.
The satellite icon on the guidance screen is RED.
COM Error The GPS receiver is not providing any data
to the navigation processor. Internal communication between the GPS receiver
and the navigation processor is not possible.
