key and select one of the three following options to determine your Trek’s behaviour when this
situation occurs.

9.15.10 Resetting GPS Position
Occasionally, the Trek will not be able to properly situate the user. For example, this may happen
in an environment surrounded by high buildings or dense trees. In situations such as these, it can
be useful to reset your position by selecting this option.
9.15.11 Update GPS satellite positions
Although the Trek automatically and regularly updates satellite positions for up to three days, this
option lets you update the satellites’ ephemeris information manually for an optimal GPS
accuracy for up to two weeks. You may have to wait up to 2 minutes for the GPS positions to be
updated on your Trek.
