Section 4 covers
Mapping Mode Operation
. It will show you how easy it
is to run the iFINDER, right out of the box. This section features a one-
page Map Mode Practice Run.
(If you've already jumped ahead and
figured out how to set up the unit yourself, and you just can't
wait any longer, turn to the Practice Run on page 32 and head
for the road with your GPS unit!)
When you come to a GPS menu command on the iFINDER screen, you can
look it up in the manual by skimming over the table of contents or index, or
by scanning through the commands in Section 4.
The iFINDER is ready to use right out of the box, but you can fine tune
and customize its operation with dozens of options. We describe how to
use general system options along with GPS options in Section 5,
System
Setup and GPS Setup Options . This section covers both Music Mode
and Map Mode options.
In Section 6, we’ll go into detail on how to search for and navigate to
points of interest, addresses and waypoints you’ve created. Finally, in Sec-
tion 7, we offer
Supplemental Material , including a list of the GPS da-
tums used, warranties, and customer service information.
How iFINDER Works
You'll navigate faster and easier if you understand how iFINDER scans
the sky to tell you where you are on the earth — and, where you're go-
ing. (But if you already have a working understanding of GPS receivers
and the GPS navigation system, skip on ahead to Section 2,
Installation
& Accessories on page 7. If you're new to GPS, read on, and you can
later impress your friends with your new-found knowledge.)
First, think of your iFINDER as a small but powerful computer. (But
don't worry — we made iFINDER easy to use, so you don't need to be a
computer expert to find your way!) The iFINDER includes a keypad
and a screen with menus so you can tell it what to do. The screen also
lets iFINDER show your location on a moving map, as well as point the
way to your destination.
This pocket-sized computer also contains an antenna and specialized
scanning receiver, something like your car radio. But instead of your
favorite dance tunes, this receiver tunes in to a couple of dozen GPS
satellites circling the earth. (It will also listen in to the WAAS satellites
in orbit, but more about that in the upcoming segment introducing you
to GPS and WAAS.)
iFINDER listens to signals from as many satellites as it can "see" above
the horizon, eliminates the weakest signals, then computes its location in
relation to those satellites. Once iFINDER figures its latitude and longi-
