The Navigator uses six (6) AA batteries, which are installed at the back of the unit. Alkaline,
rechargeable, Lithium, or Ni-Cad batteries can be used. Battery life will vary due to a variety of factors,
including surrounding temperature and the use of backlighting. You may fi nd that Lithium batteries
provide longer life in colder conditions. Saved information will not be lost when you replace the
batteries.
WARNING: It is very important to install ALL batteries with the proper polarity, positive (+)
or negative (-), orientation as indicated in the unit’s battery compartment. Batteries can
leak and cause personal injury and property damage if you install them incorrectly.
A power symbol (electrical plug) appears at the bottom of the Main Menu and in the upper left
hand corner of the Trip Information Page (see page 24) when the unit is running on external power.
When the unit is running on AA batteries, instead of the power symbol a green battery strength bar
indicator appears. The bar shortens as the unit uses battery power. To conserve battery life you can
switch to Battery Saver mode (see Owner’s Manual page 41) or you can use the vehicle power.
When the battery power falls below a certain level, the bar indicator turns red. You should replace
the batteries when this occurs. In addition, a ‘battery voltage is low’ message appears at the bottom
of the page.
To install the batteries:
1. Lift up the metal D-ring at the back of the unit and turn it ¼ turn counterclockwise to open the
compartment door.
2. Install the batteries (as shown at left and as marked in the battery compartment).
3. Turn the D-ring ¼ turn clockwise to lock the door in place.

• Observe correct polarity when installing batteries.
• Replace all batteries at the same time.
• Do NOT mix new and used batteries.
• Do NOT mix Alkaline batteries with Lithium or Ni-Cad
rechargeable batteries.
Immediately after you install new batteries, turn the unit on
to ensure that the unit’s battery strength indicator displays a
fully-charged battery condition.
If the unit does not turn on or the battery level indicator
displays a partially charged battery condition, recheck for
proper battery installation. If, after checking installation,
the battery level indicator continues to indicate a partially
charged condition, the newly installed batteries may be
depleted from long-term storage. Replace with fresh batteries.
