HD Radio technology will debut on the Cadillac XTS as a standard feature of the automaker’s Cadillac User Experience system, arriving at dealerships in spring 2012.

With the news, Cadillac said it will become the first U.S. auto manufacturer to offer HD Radio technology as standard equipment.

Cadillac Product Director Hampden Tener said HD Radio is an excellent addition to CUE, which will provide consumers with a “groundbreaking user experience for connectivity and control.”

CUE’s audio functions also include analog AM/FM, integrated iPod/MP3/smartphone media player connectivity, multidevice music indexing, SiriusXM, and applications such as Pandora.

OnStar controls are also accessible through the CUE touchscreen.

Program Service Data is transmitted as part of the HD Radio signal. PSD information such as song title and artist will display on the CUE audio screen. Audio can be paused up to 20 minutes, allowing users to resume the program if they interrupt the audio while driving.

In the Cadillac CUE system, HD Radio also features iTunes Tagging, which allows listeners to tag their favorite songs for later preview and purchase on iTunes.

With this announcement, HD Radio technology is or will be available as a factory installed feature on 23 automotive brands, according to iBiquity Digital.
