The Navigator uses an on-screen message system to alert you to unit operating characteristics. Press
key to acknowledge and return to the page you were viewing.
Using City or Postal Code May Help - More addresses or intersections were found than can be displayed.
If the speciﬁ c address or intersection you are looking for is not in the list, try entering a city or postal code
and searching again.
Antenna Shorted To Ground - Check antenna wiring or antenna placement.
Battery Voltage Low - The batteries are low and should be replaced.
Basemap Failed - The unit’s basemap has failed. Return the unit to GARMIN for service.
Can’t Unlock Maps - At least one map on the data card is locked.
Data Transfer Complete - Transfer of data to the unit from PC software has been completed.
Database Error - A waypoint or route failed to store in memory. If the problem persists, return the unit to
GARMIN for service.
GPS Turned Off for Indoor Use - GPS satellite reception has been disabled for indoor use.
Lost Satellite Reception - The unit has lost satellite signals. Check antenna connections or try moving it to a
location with a clear view of the sky.
Memory is Full - The unit’s memory is full. To reduce the amount of memory used, delete unused routes,
waypoints, or track log data.
Memory (RAM) Failed - The unit has detected a failure in its internal memory. If this message persists, the unit
is unusable - return it to GARMIN for service.
Memory (ROM) Failed - The unit has detected a failure in its permanent memory. If this message persists, the
unit is unusable - return it to GARMIN for service.
No Diff GPS Position - No differential correction data is available or not enough data is available to compute
a DGPS position.

Messages Appendix D
None Found - A search through MapSource data, using the selected criteria, has produced no matching results.
Processor Failed - The unit has detected a fault in its internal processor. If this message persists, the unit is
unusable - return it to GARMIN for service.
Route Memory is Full - Route memory is full and no more routes can be saved or added (from another GPS
unit or a PC).
Route Truncated - The route has been truncated because it was too long. There will be turns missing prior
to the destination.
Route Waypoint Memory is Full - There is no more space for map-based route waypoints (used for turns).
Safe Mode is Turned On - The action attempted is disabled while moving to prevent distractions while riding.
Sunrise, Switching to Day Mode - The map is switching to the Day Mode display.
Sunset, Switching to Night Mode - The map is switching to the Night Mode display.
That Route Name is Already Used - The route name you have entered is already being used by another route.
Too Many Maps on Data Card- The data card contains more maps than the unit software can process.
Too Many Vias for Road Navigation- The route contains too many via points (intermediate destinations). The
route can only be navigated in an off-road, or point-to-point fashion.
Track Memory is Full - Track Log memory is full. No additional track log data can be stored without deleting
old data to create memory space.
Track Truncated - A complete uploaded track will not ﬁ t in memory. The oldest track log points were deleted
to make space for the most recent data.
Waypoint Memory is Full - You have used all 500 waypoints available. Delete unwanted waypoints to make
space for new entries.
Waypoint Name Already Used - The waypoint name you have entered is already used by another waypoint.

1. The temperature rating for the Navigator may exceed the usable range of some batteries. Alkaline batteries can rupture
at high temperatures.
2. With optional GARMIN GBR 21/23 Beacon Receiver Input.
3. Subject to accuracy degradation to 100m 2DRMS under the U.S. DOD-imposed Selective Availability (SA) Program.
4. Alkaline batteries lose a signiﬁ cant amount of their capacity as temperature decreases. Use Lithium batteries when
operating the Navigator in below-freezing conditions. Extensive use of bright screen backlighting will signiﬁ cantly reduce
battery life. Low to moderate screen backlighting can signiﬁ cantly prolong battery life.

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
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
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. I
• 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.
