Initial Driving Directions

Within a few seconds of selecting a Drive To location, TeleNav GPS Navigator

calculates what it believes to be an optimal route to your destination and tells

you how to start your trip from your current location.

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.

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.

Make an alternate selection from the list. If you do nothing, this screen

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.
