32 nüvi 715 Series Owner’s Manual
Playing Audio Through Your Vehicle Speakers
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 trafc 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.
