Introduction
Product Registration
and Support
The GPSMAP 176 uses GPS technology in order to fi nd your
precise location. GPS stands for Global Positioning System, a
group of 24 satellites, circling the Earth twice a day, at an altitude
of about 12,000 miles. The satellites transmit very low power
radio signals containing position and time information, allowing
anyone with a GPS receiver to determine their location on the
Earth within 100 meters or better. For more detailed information
regarding GPS, we have prepared a booklet called “GPS Guide
for Beginners” which is available to you from our web site at
www.garmin.com.
