Gracenote®
Gracenote technology embedded
into the radio helps manage and
navigate the USB device music
collection. When a USB device is
connected to the radio, Gracenote
identifies the music collection and
delivers the correct album, artist
name, genres, and cover art on the
screen. If information is missing,
Gracenote will fill it in.Searching Music Library Using
Voice Recognition
Voice Recognition:
Gracenote
improves music search and
navigation by identifying bands,
artists, and albums names that may
be hard to pronounce, irregular
spellings, and nicknames. For
example, Gracenote helps the
system understand artist names like
“INXS” or“Mötley Crüe.” It also
allows the use of names like: “The
Boss,” “G.N.R,” “The Fab Four,” and
thousands of other famous artist
nicknames as voice commands to
access music. See Voice
Recognition on page 68.
Normalization: Normalization helps
to improve the voice recognition
accuracy for titles that sound similar.
It also helps group long lists of
genres into 10 common genres. For
example, there may be multiple rock
genres in the media library;
normalization will group all those
into one rock Genre. Normalization
default is off.To turn Normalization on:
1. Press CONFIG or Config on the Home Page.
2. Press Radio Settings, then press Gracenote Options.
3. Press Normalization to turn on or off.
Cover Art: The Gracenote
embedded database contains cover
art or album art information for the
music on the USB device. If the
music is recognized by Gracenote
and does have cover art, Gracenote
will use the cover art found in the
embedded database and display it
on the radio. User predefined cover
art will always be used first. If no

cover art is found Gracenote will
use generic Genre graphics or
images of artists.

The Gracenote database contains
attributes for Music, such as genre,
era of music, region, artist type,
mood, etc. Use this to create a
playlist of up to 30 songs "more like"

playlist will be stored in the Playlist
Menu when the device is
reconnected. If songs are removed
from the device, the system will
simply skip over those songs and
play the next available song.

recognition to create a More Like
