I don't know if this is a no brainer to others but I thought it was worth a post.

I used my smart phone's Sirius app to run through the USB port. Instant Sirius, no install!

Let me rephrase, Iphone 4, plug into USB, turn on Sirius App. , Enjoy!

I used it for 2 hours today and only ate up 14.6 mb on a 6gb data plan.

Of course you need three things to do this.

1. Smart phone with Sirius app.
2. Sirius subscription
3. 3g / 4g data plan

 

Can you change the channels with the controls on the radio or do you have to use the touch screen on the phone?

 

As far as I can tell, you have to use the Iphone's touch screen. I'll play around with it more, but it basically overrides the ipod music to work. So it's not as nice a proper Sirius install.
