Sirius Starmate 5 Coming With XM Support?

Sirius' update to its Starmate line, the Starmate 5, is currently in front of the FCC for testing, and it looks like it might have a little trick up its sleeve. The gadget includes the standard abilities to pause, rewind, and replay up to 44 minutes of live radio, a memo feature to store up to 30 favorite artists or songs and a wide-angle 5 line display, but it also might just have the ability to play XM radio stations as well.

Though the function to grab sweet sounds from its partner-to-be isn't listed in the Starmate 5's spec sheet, a memo between a testing firm and the FCC authorization staff hinted at Sirius XM interoperability. In a letter asking the testing firm to do another bandwidth test, the FCC said that it "used the satellite radio signal coming from either XM or Sirius."

If the hint means what we think it means, the Starmate 5 could be the first hybrid satellite radio receiver out on the market — kind of a bold move, considering the FCC isn't even thinking about voting on the merger until late May or early June. [Electronista]
