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.
