Turn Preview allows you to leave your current position and focus more
closely on a turn in the route ahead. A closer zoom range and large-font
data boxes will appear to help you see exactly what the road conditions
are ahead.
The Directions list gives you a detailed description of the entire route
with more information than you can see in the basic Map Mode. The
Directions list displays every step of the way, so you get a good idea of
what to expect further down the road.
The path described in the Directions list parallels the magenta route
line on your Map Mode. Every entry in the list is shown on the map's
route as a dot, as mentioned before. You can select any turn in the Di-
rections list to open a Turn Preview screen for that instruction.
These tools can be very useful when checking a route through a known
area. After the iWAY generates a route open the Directions list and
read through the steps to see if it generally matches the path you
would take. If the route is over unknown ground this can be a very use-
ful way to prepare your self for the path ahead.
Considering Temporary or Local Conditions
Unfortunately, the iWAY cannot possibly be aware of all temporary or
local conditions that could affect your course. Short-term construction,
traffic jams or local bans on U-turns could all impact the usefulness of
an iWAY-generated route.
If you are following a route generated by the iWAY and temporary or
local conditions make it impossible or inconvenient to follow the
iWAY's instructions use your best judgment. Keep driving and do your
best to keep moving toward your destination.
Whenever the iWAY notices that you have left the path it generated for
you it will begin generating a new one based on your new position. This
feature will help you when dealing with temporary or local conditions
that interfere with a route.
When construction diverts you from the route the iWAY recommended
you will often find that the iWAY recalculates your route and creates
one that matches the official detour.
The most important step in learning how to follow iWAY's routes is
practice. Use the iWAY as often as possible and pay attention to the
way it "thinks." With time you will learn exactly how to get the most
out of the navigation provided by the unit.
