Frequency Selection Tips
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, choose 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. 
FM Transmitter 
Information
The FM transmitter is intended to 
transmit your nüvi’s 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 may also affect the noise level. 
Vehicles with antennas located far 
away, such as a rear-mounted antenna, 
may experience more interference from 
outside noise sources than vehicles with 
front-mounted antennas.
As you drive, you may notice changes 
in the background static even though 
there is no FM station using that 
channel. You may 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 
may make it necessary to look for 
another frequency.
