No. It is not being fazed out. The company is now SiriusXM.
As far as radios are concerned, who knows. There seems to be only XM radio's left for purchase at the big box stores.
But try WalMart, Sears, and Radio Shack near you. No guarantees, but they may have a Sirius Starmate, or the like, lying around. Then if you need a home, ro vehicle kit, just go online and find the cheapest available.
If that is no good, then buy one online from EBay. From someone who is selling one. There are plenty available, and most people on there are reliable.
I nought my Sirius Stiletto 100 last year off of EBay, and, using PayPal, it went off without a hitch.
Or, you can try .www.craigslist.org
And look for one that someone is selling near you. But watch the price. Most people try to sell it, and get most of their initial money back.
If you can find a used Starmate/Sportster/etc... with a home and car dock, I would not spend more than $40 for everything.
TS for people who think it is worth more than that. I only spent $65 on my Sirius Stiletto 100(by itself. No docks), and that has 100 hours recording to boot. Unlike the Sportster/Starmate/etc...
But that is me. Any right minded individual who knows how much something is actually worth(not what they think or feel) will be easy to deal with.
