New York - The Sirius XM satellite-radio dock for the iPhone has been given a firm release date of Oct. 18, according to industry sources.
In addition, stores are expected to begin pre-selling the device in early October, according to one source.
The $119 XM SkyDock was unveiled by Sirius XM in August with a fall release date. The dock converts an iPhone to a true satellite-radio receiver because it includes an XM chip that can receive full XM as well as Sirius programming, including Howard Stern via a "Best of Sirius" subscription. (Without the dock, users cannot receive Stern via an iPhone app).
The XM SkyDock also connects an iPhone or iPod Touch to the car's sound system so a user's stored music can also play through the car radio.
The SkyDock is expected to be sold online and through retailers, including Best Buy and RadioShack, this fall.
