You can also choose the last line in the list, "(Press here to add...)" to
add another data box to your screen. The list of available overlay data
appears, in an expandable tree structure.
Choose the + next to any of the categories to expand it, and show the
available data within the category. You can press the - next to any ex-
panded category to hide its contents, to clear up the screen.
From this list, choose any of the data options to add it to your Overlay
Data shown. You can then modify it on the Overlay Data Shown screen

A checkbox at the bottom of the screen allows you to determine
whether the iWAY should draw boxes around the information pre-

Route Via Waypoints
Although the iWAY is designed to generate your route from your start
location all the way to your destination, sometimes you’ll want a little

tion in the list, in order, before it sends you to the final destination.
Use the Routes menu to control your route. Image at left shows Trails,
image at right shows all of the routing controls and options available
when navigating.
