To create a route for the Navigator with multiple
points or destinations, you must use MapSource City
Navigator. With City Navigator, you can create an
auto-route with any combination of waypoints, cities,
intersections and points of interest and download the
route to the Navigator.
Any intermediate point in an auto-route calculated
in City Navigator is called a ‘via’ point in the
Navigator. Refer to the MapSource Owner’s Manual for
instructions on creating routes.

GPS Information PageReference
GPS Information Page
The GPS Information Page provides a visual reference of GPS receiver functions, including current
satellite coverage, receiver status, and position accuracy. As the Navigator locks onto satellites, a signal
strength bar will appear for each satellite in view, with the appropriate satellite number (from 01-32)
underneath each bar. The progress of satellite acquisition is shown in three stages:
• No Signal Strength Bar- the receiver is looking for the satellite(s) indicated. The corresponding
number(s) on the sky view is not highlighted.
• Hollow Signal Strength Bar- the receiver has found the satellite and is collecting data.
• Solid Signal Strength Bar- the receiver has collected the necessary data and the satellite(s) is ready
for use. The corresponding number(s) on the sky view is highlighted.
Each satellite has a 30-second data transmission that must be collected (hollow signal strength bar,
as described above) before that satellite may be used for navigation (solid signal strength bar). Once a
ﬁ x has been calculated, the Navigator will then update your position, ground track, and ground speed
by selecting and using the best satellites in view.
Sky View and Signal Strength Bars
The sky view and signal strength bars give you an indication of what satellites are currently visible,
which satellites are being used to calculate a position ﬁ x, and the signal quality. The sky view shows
a “bird’s eye” view of each satellite’s position relative to the unit’s last known position. The outer circle
represents the horizon in all directions (with cardinal heading references). The inner circle represents
an elevation of 45° above the horizon. Any satellite depicted near the center is directly overhead. You
can use the sky view to help determine if any satellites are being blocked, and whether you have a
current position ﬁ x (indicated by ‘2D Navigation’ or ‘3D Navigation’ in the status ﬁ eld). You can also
set the sky view to a ‘Track Up’ conﬁ guration (instead of ‘North Up’), causing the top of the sky view
to align to your current track heading.
A hollow bar (number 17) indicates the receiver has
found the satellite and is collecting data.
Solid bars indicate the receiver has collected the
necessary information and the satellite is ready for use.

GPS Information Page
As soon as the Navigator has collected the necessary data to calculate a ﬁ x, the status ﬁ eld will
indicate a 2D or 3D status. (For ‘2D’, you may need to enter your elevation.) Receiver status is indicated
at the top left corner of the page. The status will be shown as one of the following conditions:
Searching Sky- the Navigator is looking for any available satellites in view.
AutoLocate- the Navigator is initializing and collecting new almanac data. This process can take up to
ﬁ ve minutes, depending on the satellites currently in view.
Acquiring- the receiver is collecting data from available satellites, but has not collected enough data
to calculate a position ﬁ x.
2D Navigation- at least three satellites with good geometry have been locked onto and a two-
dimensional position ﬁ x (latitude and longitude) is being calculated. ‘2D Diff ’ will appear when you are
receiving DGPS corrections with a two-dimensional position.
3D Navigation- at least four satellites with good geometry have been locked onto, and your position is
now being calculated in latitude, longitude and elevation. ‘3D Diff ’ will appear when you are receiving
DGPS corrections with a three-dimensional position.
Poor GPS Coverage- the receiver isn’t tracking enough satellites for a 2D or 3D ﬁ x due to bad satellite
geometry or due to a shaded antenna (riding between buildings, etc.)
Not Usable- the receiver is unusable, possibly due to incorrect initialization or abnormal satellite
conditions. Turn the unit off and back on to reset, and reinitialize the receiver if necessary.
GPS is Off- the unit is being used indoors and cannot be used for navigation. When the unit is being
used indoors, battery life is saved since the GPS receiver is turned off.
‘Acquiring Sats’ means the receiver is collecting data
from available satellites but has not collected enough
data to calculate a position ﬁ x.
‘GPS Is Off’ tells you the unit is being used indoors and
cannot be used for navigation.

‘Poor Satellite Reception’ Menu
If no satellites are received for several minutes (or an insufﬁ cient number of satellites are received
to determine a position ﬁ x) a message will appear, prompting you to update your approximate location
or turn off the GPS for indoor use. Updating your approximate location will ensure the Navigator is
searching for the correct satellites, and is useful if you have traveled over 500 miles with the unit turned
off. If the unit has been stored without batteries and the displayed date is incorrect, the Navigator will
not know the current positions of the GPS satellites. Selecting ‘Stored w/o Batteries’ will tell the unit
to search for any satellites that it can ﬁ nd.
The ‘Poor Satellite Reception’ prompt may appear when you ﬁ rst use your Navigator. The prompt
may also appear during normal use if the antenna is shaded or when the unit is used indoors.
The GPS Information Page indicates the accuracy of the position ﬁ x. See Appendix E for the
Navigator performance speciﬁ cations which include accuracy.
The ‘Poor Satellite Reception’ Menu gives you several
options when an insufﬁ cient number of satellites are
received to determine a position ﬁ x.
The sun and moon icons on the satellite skyview are
for reference (notice that the icons are grayed if the
sun/moon is below the horizon). You can see the sunrise
and sunset times for your current location and date on
the Time Setup Page.

GPS Information Page Options
To display the GPS Information Page Options, press
(with the GPS Information Page
displayed). The following Options are available:
• Track Up (or North Up)
• New Elevation
• New Location
Track Up- changes the sky view display from ‘North Up’ orientation to align to current direction of
travel (ground track). If ‘Track Up’ is selected, ‘North Up’ will appear as an option instead.
To change the sky view orientation:1. Use the ROCKER KEYPAD to highlight ‘Track Up’ (or ‘North Up’) and press ENTER.
New Location- forces the Navigator to search for any available satellite to determine its position. This
option is useful if you’ve relocated a long distance (greater than 500 miles) from the last location the
Navigator was used. In such instances, without initialization, the Navigator may otherwise be looking
for the wrong group of satellites.
To select New Location, highlight ‘New Location’ and press ENTER.
New Elevation- allows you to designate your approximate elevation, when the Navigator is acquiring
satellites or navigating with a two-dimensional position. By default, 2D navigation will attempt to use
the last known elevation. If the elevation shown is off by several hundred feet (or more), manually
entering your approximate elevation will enable the receiver to more accurately determine a position
To enter an elevation:1. Use the ROCKER KEYPAD to Highlight ‘New Elevation’ and press ENTER.
2. Enter your approximate elevation using the ROCKER KEYPAD, and press ENTER.
Selecting ‘North Up’ will display the sky view with
North at the top.
Selecting ‘Track Up’ will automatically rotate the sky
view to keep your current direction of travel at the top
of the display.
