Traffic Message Channel “TMC”
The GPS-500 is equipped with a built-in FM receiver to process TMC (Traffic
Message Channel) messages. The TMC is a free system to send out free traffic
information via RDS (Radio Data System). TMC might or might not be
available in your country. Please note that the GPS-500 does not support
subscription-based TMC services which are available in some countries as
an alternative to freely distributed TMC services. In case there is traffic jams
along your route the GPS-500 will show the traffic information on the map
and automatically recalculate the route. If the anticipated delay is too long,
the system will put you on an alternative route. You enter the TMC menu by
pressing the “TMC” button on the “Navigation Settings” screen.
The “Traffic Events” Menu
The main TMC window displays
all incoming traffic messages
sorted by distance from your
actual position. The traffic
information contains the type
of traffic, the road number and
the length of event. You can
have a look at each individual
traffic event on the map by hit-
ting the “Show” button. Simply
hit “Back” on the map view to
go back to this menu.
The “Settings” Button will route you to a subsequent settings menu where
you can make additional adjustments of the TMC system behaviour.
The “TMC Settings” Menu
Normally the GPS-500 will
automatically tune to the best
FM station. If you would like to
tune to a preferred FM station,
please disable "Auto" and use
the "+" and "-" Buttons. You are
though able to select the FM
stations which are used to
receive TMC messages.
“Exclude selected station” will
deny the FM station which is
currently in use. This will help
you to avoid certain stations
with poor TMC performance.
Thereafter the device will
search for an alternative FM
station. Press “Show excluded
stations” to enable denied
stations. The system will again
include them in its searching
process.
