See the Important Safety and Product
Information guide in the GPS device box
for product warnings and other important
information.
The Garmin GTM 25 delivers Trafc Message
Channel (TMC) information, including road
conditions and trafc delays, to your GPS
device. When trafc information is received,
your GPS device displays trafc delays on the
map. This information is used to avoid trafc
delays and nd the fastest routes.
The trafc information is broadcast over the
FM Radio Data System (RDS). For coverage
areas, refer to the Garmin Web site at
www.garmin.com/trafc.
To receive trafc information, the trafc
receiver must be connected to the GPS device,
connected to an external power source, and the
trafc receiver and GPS device must be in data
range of an FM station transmitting TMC data.
