HD Radio™ Technology is the digital evolution of analog AM/FM radio. Your
radio product has a special receiver which allows it to receive digital broadcasts
(where available) in addition to the analog broadcasts it already receives.
Digital broadcasts have better sound quality than analog broadcasts as digital
broadcasts provide free, crystal clear audio with no static or distortion. For more
information, and a guide to available radio stations and programming, refer to
www.hdradio.com.
“HD Radio features included in Lexus radios: 
Digital Sound - HD Radio broadcasts deliver crystal-clear, digital audio quality to
listeners. 
HD2/HD3 Channels - FM stations can provide additional digital only audio pro-
gramming with expanded content and format choices on HD2/HD3 channels.
PSD - Program Service Data (PSD) gives you on-screen information such as art-
ist name and song title. 
iTunes Tagging - Listeners can tag (store) songs they like for later review and pur-
chase through iTunes. 
Artist Experience - Images related to the broadcast are displayed on the radio
screen, such as album cover art and station logos.”

Reception sensitivity

●

Maintaining perfect radio reception at all times is difficult due to the continually chang-

ing position of the antenna, differences in signal 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.
