FM Transmitter Tips
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.
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.
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 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.
