Well, the 396 does have a perfectly good XM radio. Still, I'm keeping the Roady2. I like being able to have the instantaneous ability to shut off the music (click the Roady2's power button), change the channel, etc.
With the 396, it takes many more clicks and a couple of screen changes just to get to the XM channel selection. Lowering/raising the volume is pretty easy -- just click the power button once, then click up/down a few times. But it's still more clicking than I'd rather do for simple stuff.
The Roady2 is super light, consumes negligible power, and is quicker to mess with. So for now it stays.
