If you have an older receiver you will need an adapter (2 wire to 1 wire)

A quick Google search turned up this.

Here is a pic of one of the newer small ones. There are a few on the market now.

 

Amazing thanks a lot guys!!!

Now for another question.... what is better... sirius or xm?

I like to listen to rap, r&b, dance, trance... hip hop.. you know, anything with a beat.

Should i get xm or should i get sirius?

Also, i live in canada, will they work here?

taste is subjective but generally opinions coalesce around the following:

XM has more music. Broader, deeper playlists. Much bigger music library.
Sirius is much more repetitive. Very hits based.

They both work in Canada just fine so long as you're below the arctic circle.

For my money, XM is vastly superior, because I only listen to music and don't care much about anything else.
