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.
