FM Transmitter Tips
The FM transmitter is intended to transmit your
StreetPilot’s audio to your car stereo’s antenna.
Do not adjust your FM settings while you are driving
your vehicle.
When searching for an appropriate FM frequency on
your vehicle’s radio, 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.
Touch
Test to play a sample audio output over your
vehicle’s stereo. If the sound is not to your liking, try a
different frequency and touch Test again.
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.
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.
The distance between the 12-Volt adapter, the
StreetPilot, and the vehicle 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.
