Mercedes-Benz is testing iPod-compatible Audio Books at the New York Auto Show, which is taking place at the Jacob Javits Convention Center in New York City until April 2. The Audio Books are designed to educate potential Mercedes buyers about a car’s features by providing digital “walk-around” audio narrations with an iPod. Consumers at the show can download the Audio Books to their own iPod for $2.95, or use loaner iPods for free. Mercedes-Benz said downloads of the Audio Books will also be available on the iTunes Music Store. The car maker has developed Audio Books — that cover everything from the engine to trunk — for the M-Class, CLS, SLK, and SLR McLaren. All proceeds from the Audio Book sales during the show will be donated to Automotive High School in Brooklyn, New York.
