inaccurate or incomplete information due to
the passage of time, changing circumstances,
and due to the nature of the sources used.
Please observe the actual traffic
circumstances and regulations at all times
while driving.

account for in any way; information regarding
traffic and road laws; vehicle specifications
including weight, height, width, load, and/or
speed restrictions; road conditions including
road slope, grade, and/or surface conditions;
obstruction information including bridge and
tunnel height and width, and/or other

On Bluetooth communication
(NV-U94T/U74T only)

• Bluetooth wireless technology operates within

a range of about 10 m (about 30 ft).
Maximum communication range may vary
depending on obstacles (person, metal, wall,
etc.) or electromagnetic environment.

• When using the Bluetooth function, install the

unit within 60 cm (about 20 in) from the driver.

• The following conditions may affect the

sensitivity of Bluetooth communication:
– There is an obstacle such as a person, metal,

or wall between this unit and Bluetooth
device (cellphone, etc.).

– A device using 2.4 GHz frequency, such as a

wireless LAN device, cordless telephone, or
microwave oven, is in use near this unit.

• Because Bluetooth devices and wireless LAN

(IEEE802.11b/g) use the same frequency,
microwave interference may occur and result in
communication speed deterioration, noise, or
invalid connection if this unit is used near a
wireless LAN device. In such as case, perform
the following:
– Use this unit at least 10 m (about 30 ft) away

from the wireless LAN device.

– If this unit is used within 10 m (about 30 ft) of

a wireless LAN device, turn off the wireless
LAN device.

– Install this unit and Bluetooth device as near

to each other as possible.

• Microwaves emitting from a Bluetooth device

may affect the operation of electronic medical
devices. Turn off this unit and other Bluetooth
devices in the following locations, as it may
cause an accident:
– where inflammable gas is present, in a

hospital, train, airplane, or a gas station

– near automatic doors or a fire alarm
