Traffic tie-ups can't always be prevented. But
with Garmin's GTM 20, they can often be avoided.
Avoid Traffic Tie-ups
The GTM
20 is an integrated FM TMC (Traffic Message Channel) traffic
receiver, antenna and cigarette lighter adapter. Designed
exclusively for the American version of certain products,
it receives digital information (where available) on traffic
and road construction tie-ups that your compatible Garmin
unit uses to offer an alternate route. TMC data, available
in a fast-growing number of cities throughout North America
and Europe, gives prompt, accurate notification of accidents,
road construction, police, or emergency action, etc. — so
you can visually monitor traffic flow and, if necessary,
avoid traffic tie-ups.
Receive Real-time Traffic Data
In most
areas, depending on the service provider, TMC traffic broadcasts
are continuous — there's no waiting for scheduled traffic
news updates or random alerts. With the GTM 20, you see traffic
developments in real-time, as they happen, so you can make
the right decision sooner. The system alerts you when a traffic
problem is on your route and proposes an alternate route
to avoid the incident. Because traffic broadcasts are received
via a "silent" FM data channel, you can still listen to music
or news programming on your car radio without interference
from incoming FM traffic data transmissions
.The GTM 20 is a portable, all-in-one antenna, traffic receiver,
and 12-volt cigarette adapter that does not require professional
installation.
