Garmin 855 Guida Utente

Playing Audio Through the Vehicle’s Speakers

For best results, select a frequency below 

90.1 FM.
When searching for an appropriate FM 

frequency on your FM stereo, look for 

an unused frequency that has steady, 

consistent static. If you hear slight noises 

and sounds in the background of the 

static, select a different frequency.
As you travel, you might need to change 

the frequency for the FM transmitter. 

A frequency not used by a radio station 

in your area might be used by a station 

elsewhere. 

The FM transmitter is intended to 

transmit nüvi audio to your FM stereo.
Do not adjust your FM settings while 

you are driving your vehicle. 

The distance between the vehicle power 

cable, the nüvi, and the FM stereo 

antenna might also affect the noise 

level. Vehicles with antennas located far 

away, such as a rear-mounted antenna, 

might experience more interference from 

outside noise sources than vehicles with 

front-mounted antennas.
As you drive, you might notice changes 

in the background static even though 

there is no FM station using that 

channel. You might notice this as you 

drive through intersections where certain 

kinds of traffic lights or other municipal 

electronic systems are operating. You 

might also notice this effect when the 

terrain changes, allowing distant stations 

to be received by your car stereo that 

were not received when you made your 

initial frequency selection. These and 

other sources of electrical interference 

might make it necessary to look for 

another frequency.
