Important Safety Information
WA NING: It is the user’s responsibility to use this product prudently and maintain safe-driving
practices at all times. This GPS should be used only by someone able to clearly understand the
instructions and able to operate the controls. For proper safety we recommend that a passenger
operate the GPS unit. However, in cases where you are alone, it is recommended that you pull
over to make any adjustments to the GPS unit. It is also important to make sure that the unit is
secure, does not block the driver’s field of vision, and will not become a hazard in case of an
accident. Do not mount or place the GPS unit on an air bag equipped steering wheel or passenger
area. In case of an accident this can be deadly.
The Global Positioning System (GPS) is operated by the government of the United States, which
is solely responsible for its accuracy and maintenance. The system is subject to changes which

The detailed mapping software is provided by NAVTEQ and Netropa. The detailed mapping
software is as accurate and detailed as possible. Whenever maps are digitized, there is still a
possibility that some inaccurate or incomplete data can be found. It is because of these
inaccuracies that the WGPX-545/550 is a travel aid and is not intended for precise measurement
in navigation or aircraft use.
Differences between manufactured and shipped versions of the software may be present; this
software may be updated frequently. If the descriptions in this manual are different from your
software version, please follow the software version currently on hand.
Software Use Terms
Copyright laws protect the WGPX’s operating system and internal mapping software. Whistler’s
wMap mapping software is copyrighted by their respective owners. Please carefully review the
software agreement information enclosed in the Whistler’s wMap Mapping Software User’s
