Navigation/Radio System
The display screen is located in the center of the
instrument panel.
Your vehicle may have an AM-FM navigation radio
system that includes a Radio Data System (RDS) with
program type selections (PTY) that will seek out the kind
of music you want to listen to. The radio system can
also communicate with your navigation system to
broadcast announcements on traffic and emergency
alert communications. For information on how to use this
system, see the “Navigation/Radio System” supplement.
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.
