Understanding Radio Reception

AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and go.
Understanding DVD Distortion
You may experience video distortion when operating
cellular phones, scanners, CB radios, Global Position
-
Systems (GPS)*, two way radios, mobile fax, or
walkie talkies.
It may be necessary to turn off the DVD player when
operating one of these devices in or near the vehicle.
