9.9 Backtrack (retrace steps)
Backtrack is a feature that allows you to retrace your steps and return to your point of origin.
There are two Backtrack options possible.
The first option is Backtrack Current Session: This option allows you to backtrack your current
session, meaning that you can be guided from your current location back to your starting point
(after getting a GPS connection).This option is useful when you wish to return immediately upon
reaching your destination. For example, when you leave home, you start your Trek. You reach
your destination. Because you don't intend to stay very long, you leave the Trek on. In this case, if
you wish to be guided back home, you will use the Backtrack Current Session option.
To Backtrack your current session (without turning the Trek off and back on):
1. Press and hold the 9 key.
2. You will be asked if you want to backtrack your current session or your previous session.
Press Confirm to backtrack current session. The system will provide you with instructions
to guide you back to your point of origin. A message will inform you when you have
reached your destination.
The second option is called Backtrack Previous Session. This option allows you to backtrack your
previous session. The Trek automatically records your pedestrian travels during the last power
on/off session. This option is useful when you wish to return to your point of origin, but have shut
the Trek after reaching your destination. For example, when you leave home, you start your Trek.
You reach your destination. Because you wish to stay there for a while, you shut off your Trek.
When you decide to leave and return home, you power the Trek back on. In this case, if you wish
to be guided back home, you will use the Backtrack Previous Session option.
To Backtrack previous session (after a Power off):
1. Press and hold the 9 key.
2. You will be asked if you want to backtrack your current session or your previous session.
Press and hold Confirm to backtrack your previous session. The system will provide you
with instructions to guide you back to your point of origin. A message will inform you
when you have reached your destination.
It is important that you keep in mind that the "previous session" track used to return to your point
of origin will not be kept indefinitely. Only the track created up to the last Power off will be kept in
memory. It will be replaced by a new one the next time the unit is powered on.
To Cancel Backtrack
Press and hold the 9 key. You will be asked to confirm. If the Confirm button is pressed within 15
seconds, the Backtrack feature will be deactivated.
Note: On a full battery, the system will be able to Backtrack a route traveled while the device is
turned on, representing a period of several hours.
Note that the Backtrack feature is not available when traveling by vehicle. Only the last pedestrian
portion of the distance traveled after an in-vehicle session will be kept to retrace your steps.
9.10 Getting guidance to a landmark
Trek can provide guidance instructions from the current user location to a selected landmark
chosen as a destination. Guidance instructions are similar to those provided by Trek when
following a pre-established route. However, instructions to reach the destination landmark are not
recorded as routes.
