After you've learned the basics (or if you already have some GPS expe- rience), you may want to try out some of the IntelliMap 642c's many advanced navigation features. That brings us to Section 4, Advanced GPS Operations. This section contains the rest of the unit's GPS com- mand functions, organized in alphabetical order.
When you come to a GPS menu command on the IntelliMap 642c's screen, you can look it up in the manual by skimming over the table of contents, just flipping through Section 3 or scanning through the command portion of Section 4.
This unit is ready to use right out of the box, but you can fine tune and cus- tomize 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. Section 5 is organized in alphabetical order.
In Section 6, we go into more detail on one of the IntelliMap 642c's most remarkable capabilities — Searching. We'll introduce a search example in the Basic GPS Operation section, but there are so many map items you can search for, we had to give this function its own section in the manual! For example, did you know this unit can look up business phone numbers, functioning as a virtual Yellow Pages? We’ll show you how in Section 6.
Finally, in Section 7, we offer Supplemental Material, including a list of the GPS datums used, warranties and customer service information.
Now, if you're into the fine details, glance over the next segment on specifications to see just how much GPS power your IntelliMap 642c con- tains. It's important to us (and our power users), but, if you don't care how many watts of power the unit has, or how many waypoints it can store, skip ahead to important information on how our GPS works, on page 4.
