Lowrance 250c 操作指南

1 

And, how this manual can get you out on the road, fast! 

Welcome to the exciting world of turn-by-turn GPS navigation. Before 
you grab the iWAY 250c

™ GPS unit and begin installing it, please give 

us a moment or two to explain how the manual can help you get the 

best performance from your mapping GPS receiver and MP3 music 

player. Our goal for this book is to get you on the road fast with a 

minimum of fuss. 

The manual has been designed so you don't  have  to  read  the  whole 
thing from front to back for the information you want. At the start (or 

end) of each segment we will tell you what content is coming up next. If 

it's a concept you are already familiar with we will show you how and 

where to skip ahead for the next important topic. We have also made it 

easy to look up any tips you may need from time to time. Here's how: 
The manual is organized into five sections. This preface will introduce 

you to GPS, your iWAY unit and the manual’s organization. The first 

section will help you install the iWAY in your vehicle. We also will 

show you how to use the USB cable to connect the iWAY to your PC. 

We will finish by describing some of the available accessories. 

Section 2 covers Mapping Mode Operation. It will show you how easy it 

is to run the iWAY right out of the box. This section features a one-

page GPS Practice Run. If you have already jumped ahead and figured 

out how to install the unit yourself turn to the Map Mode Practice Run 

on page 12 and head for the road with your GPS unit. 

In Section 3 we leave Mapping mode and introduce you to Music Mode 
Operation. The manual will explain everything you need to know about 

getting music into your iWAY, arranging the files on your memory card 

and creating and using play lists. If you are in a hurry to get some mu-

sic playing skip to the Music Practice Run on page 21. To learn how to 

copy music files to the iWAY see the included supplemental document 
"Making USB Connections Between iWAY 250c

™  and Computers." 

Section 4 describes the Options Menu, the commands used to configure 

settings such as screen brightness, sound levels and units of measure. 

We will also show you how to use features like the Trip Calculator. 
Finally, in Section 5, the manual will go into detail on how to search for 

and navigate to points of interest, addresses and contacts you have cre-

ated. We will also offer tips on how to understand and follow the auto-

matic turn-by-turn routes you have created. Before we go any further 

we would like to take just a moment to explain how the iWAY works.
