Get a ROKU. They are cheap. Plug it into your TV, or amp depending on how you wire stuff, and download the app.
Its free if you already have a satellite radio subscription.
I agree with this duckland23. Go get a ROKU. Don't spend the money on an antenna for the receiver. Try this first.
It looks like your receiver has 4 HDMI inputs, and 1 output. It is a 2006 model, but it "should" passthrough sound/picture just fine to your TV(plus your speakers connected to your receiver).
Check and see what type of account you have with SIRIUSXM with regards to your car connection. They may be offering you streaming, and you don't even know it.
An easy way to find out is to either go into your account online using a computer.
Or download the SIRIUSXM APP onto your smartphone, if you have one, log in with your online credentials, and see if it will let you stream their service to your phone. Do this in your home using your Internet service. If you can, great. If not, then there are a few things you need to do.
You DO NOT NEED the antenna for the pioneer receiver. It is just a waste of money at this point. The receiver in your car, if it is the built in radio, is using the SATELLITES IN SPACE to receive the info it is getting, NOT INTERNET.
You need to find out what service, by either your online access or by calling them, you have from SIRIUSXM. After you find out, you will know the next steps you need too take.
But don't do anything until you find that out first, and report back here.
