Use the Routing Options menu to control how iWAY generates routes.
When generating a route, the iWAY is able to analyze certain types of
roads or turns and adjust their value to either prefer or avoid them.
Preferred road types will occur more often in your routes – the iWAY
will deliberately try to take those types of roads. Road or turn types
that you Avoid will show up less, although the iWAY may have to gen-
erate a longer route to avoid them.
The three slider controls on this page let you control how much you
want to avoid or prefer the associated options when generating a route.
The farther you move the slider to the left or right, the more it will af-
fect the routes generated by iWAY. If you change these values signifi-
cantly and notice that your iWAY has begun generating poor routes, try
using the
R
ESET TO
D
EFAULTS
button to see if that fixes the problem.
You can use the R ECALCULATE R OUTE
button to automatically generate a
new route to the same destination using the new preferences. Take ad-
vantage of this option when you're trying to learn the right amount of
avoidance, to make sure the iWAY gives you just what you want.
Avoid Cross-Traffic Turns
Use this option to avoid turns across busy lanes of traffic. The iWAY
will not avoid cross-traffic turns at major intersections, where you will
likely have a protected turn at a traffic light. As with all of these set-
tings, try changing it a little at a time. Sometimes you'd have to drive
miles out of your way to avoid taking a cross-traffic turn somewhere in
your route. Then again, sometimes it's worth it. Practice with this set-
ting to find the value that's right for your driving experience.
Prefer/Avoid Toll Roads
By default, toll roads have a fairly high value in iWAY's route genera-
tion, because they are generally high quality roads with high speed
limits, allowing you to get where you're going faster.
