Garmin 855 Guida Utente

Using FM Traffic

The traffic receiver is included in some 

nüvi packages. 
Use an FM TMC (Traffic Message 

Channel) traffic receiver to receive 

traffic information that is broadcast 

over the FM Radio Data System. For 

information about FM traffic receivers 

and coverage areas, see 

www.garmin 

.

  nOTe: Garmin is not responsible for 

the accuracy of the traffic information. 

The FM traffic receiver receives 

signals from the traffic service 

provider and displays that information 

on your nüvi. 

  nOTe: The FM traffic receiver and 

the nüvi must be in data range of an 

FM station transmitting TMC data to 

receive traffic information. 

  nOTe: If your FM TMC traffic 

receiver has an antenna with suction 

cups on it, route the antenna on your 

windshield vertically using the suction 

cups.

The green Power LED lights when 

connected to external power. The Status 

LED indicates the signal reception:

Yellow dot-dash flashes—

determining which country you are 

currently in.
Yellow solid—searching for signal.
red solid—momentary sync loss.
Green solid—normal traffic data.
