■HD Radio™ Technology troubleshooting guide
■Reception sensitivity
●Maintaining perfect radio reception at all times is difficult due to the continually chang-
ing position of the antenna, differences in si gnal strength and surrounding objects, such
as trains, transmitters, etc.
●The radio antenna is mounted inside the rear window. To maintain clear radio reception,
do not attach metallic window tinting or other metallic objects to the antenna wire
mounted inside the rear window.
