Selecting Track Mode — Allows you to set how often the Meridian stores
track points. Setting the mode to “OFF” stops the Meridian from
saving any new track points. In “Auto” or “Auto Detailed” mode, the
Meridian uses a method for track point storage that maximizes memory.
Using Auto, you will see more points on and near turns and less points
on straight stretches of the map. You also have the option of selecting
fixed intervals for track point storage.

Setting the Track Mode to “OFF” will cause severe
limitations to the ability of your Meridian to create a
backtrack route. The same temporary waypoints used to
create the displayed track are used to compute a backtrack
route. Therefore, it is highly recommended that you use the
“Auto” Track Mode whenever possible.
Auto vs. Auto Detailed. You will notice two of the options for the
Track Mode are Auto (default) and Auto Detailed. Basically, both
options behave the same. While your are travelling in a straight line,
only a few track points are taken, but as you turn the Meridian increases
the rate of track points. This allows for a good representation of your
track with minimal track points stored. Auto Detailed performs exactly
the same as Auto, but has the base rate of track points saved increased.
This allows a more detailed track then Auto to be taken, while at the
same time saving memory over a fixed rate.
