MSG (Message): If the current station has a message, MSG will appear on the display. Press the MSG button, to see the message. If the whole message does not appear on the display, parts of the message will appear every three seconds until the message is completed. To see the parts of the message faster than every three seconds, press the MSG button repeatedly. A new group of words will appear on the display with each press. Once the complete message has been displayed, MSG will disappear from the display until another new MSG is received. For XM™ (48 contiguous US states, if equipped), press the MSG button while in XM mode to retrieve four different categories of information related to the current song or channel: Artist Name/Feature, Song/Program Title, Channel Category. Each of the four information types may have multiple pages of text. To reach a category, press and release the MSG button repeatedly until the desired type is displayed. If there are multiple pages of text for the information selected type, the radio will automatically display all the pages for that type at a rate of about one page every three seconds before timing out and returning to the default display. You may override this feature by pressing the MSG button to review all of the pages at your own pace. 3-88
