3. If you are not moving, TeleNav GPS Navigator may not know your
direction of travel, so the first few driving directions may be incorrect
since TeleNav GPS Navigator may initially make an incorrect
assumption. However, once you start moving, TeleNav GPS Navigator
learns your direction of travel and provides an updated set of driving
directions.
For more information about navigation views, see page 28 .
GPS Origin Refinement
If you are using GPS navigation and you are in a parking lot or similar area where
your location does not exactly map to a specific street, you may see a pop-up that
shows TeleNav GPS Navigator’s best estimate of what street you are on. This
gives you the opportunity to change the starting street.
If you choose to change the starting street, a list of neighboring streets appears,
and you can make an alternate selection from the list. If you do nothing, the first
pop-up disappears after a few seconds, and TeleNav GPS Navigator uses the
default street as the starting location.
If you are not sure which street you are on, simply start driving. TeleNav GPS
Navigator detects your current location and recalculates your driving directions as
needed.
Audible Guidance Tones
TeleNav GPS Navigator delivers audible guidance tones (beeps with a recognizable pitch) as you drive, in addition
to spoken audible directions. A preparatory audible tone is typically heard no less than 30 seconds before reaching
a turn, and an action audible tone is typically heard no less than 10 seconds before reaching a turn. The
preparatory audible tone may not be sounded if the distance to the next turn only allows time for the action tone.
The lead times for the audible guidance tones are increased proportionally to your driving speed. For example, this
allows more time for changing lanes before a turn if you are driving at highway speeds as opposed to driving more
slowly on local streets.
Miss a Turn?
Whenever you miss a turn, turn the wrong way, turn too early or too late, or otherwise get off the planned route to
your destination, TeleNav GPS Navigator automatically creates a new route to your desired destination, and an
audible tone announces that a new set of instructions is available.
If you realize you have missed a turn or have otherwise gotten off the route, just keeping driving. TeleNav GPS
Navigator detects your current location and recalculates a new set of driving directions to get you back on track.
