Sirius radio

I have Sirius radio in my truck. Any of you guys know of a Sirius unit that can be somehow mounted to a bike to use with in helmet speakers (with a cord, not wireless. ) I've been to their site but there's lots of radios; who know which might mount on a bike?

Some Garmin Zumos have XM built in with bluetooth to connect to helmet speaker. Some have mounted portable XM receivers on their bikes but I don't know if they are waterproof. and there are various ways to get signal to helmet speakers.

I listen to SiriusXM (Opie and Anthony) every morning on my way to work. I use the iPhone App paired with the Sena SMH05 bluetooth unit in my helmet.

What is the charge for the use of SiriusXM on the iphone?

Stand alone SiriusXM Internet Radio is $14.49/mo or add-on to Premier or Select package for $3.50/mo
