The Pioneer XM2go satellite radio is a portable, hand-held unit for listening and recording/time-shifting XM Satellite Radio's 130-plus digital radio channels virtually anywhere.

This, and the Tao XM2go, are part of the expanding line-up of XM's new XM2go Portable Handhelds set arrive at retail stores in spring 2005.

All the units in the XM2go product line have two listening modes: a live mode and a memory mode for storing and playing back XM programming. The live mode enables users to listen live to XM's content. The time-shifting memory mode (called "My XM") allows users to store five hours or more of content with the press of a button, even when the unit is not in use.
