General Information■Accuracy of vehicle positionArea in which GPS signals cannot be received
Because the radiowave signals from the GPS satellites travel
primarily by line of sight, the navigation system might not be
able to receive the signals in the areas described below.
(If the GPS mark does not appear on the map screen, it
means that the GPS radiowave signals are not being
properly received.)
(1) Inside a tunnel
(2) Inside a building
(3) Under a three-dimensional road system such as for high-
speed roads
(4) On boulevards lined with trees
(5) Between buildings
(6) Under a cliff or in a cave
• If the GPS antenna or its surroundings are blocked by an
obstacle (including cargo), it might not be possible for the
system to receive the GPS radiowave signals.
• If multiple paths are created due to the reflection from
buildings, a large measurement error could occur, causing
the vehicle’s mark to deviate from its actual position.Deviation of the vehicle’s position mark
The vehicle’s position mark could deviate from its actual
position when the vehicle is being driven under the
conditions listed below or due to conditions of the GPS
satellites.If the vehicle travels on a road whose actual shape differs
from that in the map data, the vehicle’s mark could deviate
from the actual position. The correct position will eventually
appear on the screen through the correction function. If the
screen does not show the correct position for an excessively
long time, correct the current position or make an automatic
correction.
(1) The vehicle’s mark could appear on a parallel road.
(2) When the road splits into a narrow Y, the vehicle’s mark
could appear on the other fork of the Y.
(3) When the vehicle makes a right or left turn, the vehicle’s
mark could appear on one street ahead or behind.
(4) If the vehicle is transported by means other than the
vehicle’s own power, such as on a ferryboat, the
vehicle’s mark will remain in the position it was before
the transport until the system can calculate the position
through the GPS.
(5) When the vehicle is driven on a steep incline, the
vehicle’s mark could deviate from its actual position.
(6) If there are continuous gradual curves in the same
direction, the vehicle’s mark could deviate from its
actual position.
(7) If the vehicle is driven in a zigzag pattern, such as
through frequent lane changes, the vehicle’s mark could
deviate from its actual position.
(8) If the vehicle is placed on a turntable, such as in a
parking area, and turned with the ignition OFF, the
vehicle’s mark could deviate from its actual orientation.

FCC WARNING
This equipment may generate or use radio frequency energy.
Changes or modifications to this equipment may cause harmful
interference unless the modifications are expressly approved in the
instruction manual. The user could lose the authority to operate this
equipment if an unauthorized change or modification is made.
NOTE
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment may
cause harmful interference to radio communications, if it is not
installed and used in accordance with the instructions. However, there
is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio
or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
NOTE
This Class B digital apparatus complies with Canadian ICES-003. CAUTION
