Use the map to see where your units are now. You choose the accounts, narrow the list to the units you care about and, for one unit, let the map follow it.
A dealer account opens on its own account, which owns no units. A consumer account with sub-accounts can add their units too.
In the side menu, select Units > Tracking.
The map opens with the unit list in the dock.
On the scope bar, select the account button.
The Account scope dialog opens.

The list and the map shrink as you type. A results panel also lists matching places, units, drivers and geofences. See Tracking screen.
Select a status button, for example Offline.
The list shows only units in that state. The number on each button is how many units of your scope are in that state.

Select Labels, then select one or more labels.
Only units with any of those labels stay. Show all clears the choice.

If nothing matches, the list reads "No units match these filters". Select Clear filters.
In the unit list, select the checkbox of a unit.
The unit appears on the map. The count at the top of the list goes up by one.

Optional: clear the checkbox of a unit to take it off the map. It stays in the list. Select None to clear the map.

To plot a few units out of many, select them first. Ctrl-click or Cmd-click adds a unit to the selection, and Shift-click selects a range. Then select Plot only selected at the bottom of the dock. The map shows only those units. See Unit list.
In the unit list, point at the unit's row and select Follow.
The map moves to the unit and a note at the top reads "Following" and the unit name.

To stop, select Stop in the note, or press Esc.
The map stays where it is. Dragging the map also stops it.
You can also follow from the unit card, with Follow. See Unit card on the map. Follow is unavailable for a unit that has no position.
Select Fit to plotted units, the crosshair button at the left of the map. The map zooms to show every plotted unit. Selecting a label name in the list fits the map to the units of that label.

The markers move when the units report. You do not need to refresh. The address in your browser keeps your accounts, labels, search and status, so you can bookmark the view or send it to a colleague.
