For our example, though, we'll assume we're running low on gas
and need the first gas station available, so we’ll just use the iWAY’s
default Find By setting,

The list of search results contains two entry fields at the top, and three
columns across the bottom of the screen. The first column contains the lo-
cation's name, and fills most of the screen. The contents of the second and
third column depend whether or not you're
currently navigating to a desti-
nation. If you're not navigating, you will see the distance and bearing from
your current location (or cursor position) to the listed location. If you're
already on a route, though, the iWAY will use these two columns to show
the To Exit and From Exit distances to help you manage your trip.
Using the "To Exit" and "From Exit" Distances
Whenever you're following a generated route and you perform a search,
the distance from your current location to any of the result locations
will be divided into two columns. These columns are labeled "To Ext"
and "From Ext." For any given POI in the list, you can add the values
in the two columns to find out exactly how far away it is.
It's very useful to have this information broken into two values, though.
In order to make trip planning easier, all POI searches are projected
along your current route. When you try to find the nearest gas station,
then, the iWAY looks ahead the way you're traveling and tries to help
you pick the most convenient choice.
To do this, it generates a route to each of the locations in the list,
sticking to your current route for as far as possible. When it finally has
to leave your route (take a detour), it marks the spot where it leaves
your current route. The distance in the "To Ext" column shows how far
along your current route it is before you detour to get to the POI. The
"From Ext" column shows you how far away from your current route
the POI is – how long the detour is.
So if you're on a cross-country trip, you might choose to go to a gas station
that's fifteen miles away, if it's only a quarter mile off the highway, in-
stead of a gas station five miles away that's five miles off your route! Then
again, if your Low Fuel warning light is on and you're driving on fumes,
you might prefer the closer gas station. The iWAY provides you all the
details, so you can choose the right destination for
your travel plans.
Using the Name Filter
Sometimes a search returns far too many results to include the one you
want, or maybe just more results than you feel like scrolling through.
The Name Filter on the search results list helps you narrow down the
list to just those items containing a particular set of letters.
