5. INITIALIZING YOUR GPS RECEIVER

Before using your BU-303 GPS for navigation (especially for the first time), the receiver must obtain a
local GPS fix (coordinates) of the current position. To do this, take your laptop (with your USB driver
and the mapping software loaded and configured) to an open area that has a clear view to the sky
(such as a park or empty field). Start your software (or the included Mac_GPSutility program) and wait
for initialization of the GPS to complete. This may take a few minutes depending on various factors
such as the distance of the current coordinates from the last time the GPS receiver was activated, GPS
signal strength and surrounding terrain (tall trees and buildings can block the satellite signals). Once the
RAW GPS data is displayed onto the screen, if applicable for your software, a fix has been initialized
(red LED on the GPS will also start to flash). In some cases initialization can take up to several minutes
depending on the conditions mentioned above before complete GPS data will be displayed on the
screen.
Coordinates scrolling with zero's means that the port connection is correct, but the satellite data is not
being received yet (possibly still initializing or in a bad area for satellite reception).

6. USING THE BU-303 GPS RECEIVER

Once the BU-303's driver and your personal mapping software have been installed and configured
properly, you can begin to use Your navigation system by plugging the BU-303 into your laptop's USB
port and launching your mapping software. If you don't have a mapping, or navigation software to try
out your new GPS receiver, we've included a utility called "GPS Information" so that you can test the
function of your BU-303. This utility is located within the "GPS Test" directory on the CD-ROM or can
be download from our web-site.
Always select an area in the vehicle where the GPS unit will be secure and not obstruct normal driving,
visibility and safety, but still maintaining a "view to the sky" in order to receive satellite data.

7. FAQ's

How Do I Enable a Root Account
The "root" user (also known as the super user) is the most powerful UNIX account. The root account
can do anything to any file or folder, anywhere on the system. For that reason, Globalsat/USGlobalsat
cannot recommend, nor support users who attempt modifications of the 'root user" as it's considered
quite dangerous, and only needs to be used (occasionally) by advanced users.
Because of the dangers of operating as root, Apple has chosen to hide the root account in OS X Final.
However, there are a number of ways to enable it. The easiest is to boot off the install CD, and look
under the Install menu for the "Password Reset" option. You can use this to change your own
?
