An audio chip implanted inside the mailer—which lends some extra weight and “lumpiness” to the piece—is activated when the package is opened. A computerized voice similar to those found in GPS systems says “Prepare to turn right. [pause] Turn right. [pause] Your destination is approaching on the left. [pause] You have arrived at your destination.” The two interior panels may explain the features and benefits of the navigational system and promote the multimedia Motorola RAZR as a great phone to use with the service, but it’s the voice—demonstrating how clear and audible the system is—that really sells the product.
