Question about the Onyx EZ Radio with Vehicle Kit Home Kit and listening on 2 devices

My mom currently has SiriusXM built into her Chevy Cruise and I pay for the subscription, so I got a email saying for $50 I can get a Onyx EZ Radio with Vehicle Kit + Home Kit and 3 free months. Thing is I don't need the car kit but the home kit sounds cool. Can she listen to both the built in Chevy cruise radio and a home radio with the same account or will I need to upgrade the account so both radios will work = more money? Also I guess the home kit doesn't come with a speaker/s so whats a good cheap speaker that works with the home kit?

Two radios = two subscription fees. But you would probably be able to get a lower rate on the second radio. Call SiriusXM Customer Care at 1-866-635-2349.

The portable onyX receiver -- yes, that's how they spell it -- is a "Dock & Play" radio. SiriusXM offers a portable speaker dock which runs on batteries or electricity. It retails for $119.99.

If you want a cheaper alternative, you can purchase a home docking kit that will allow you to play the onyX on any stereo system with an auxiliary input:
