How can I get XM satellite radio into my 04 coupe?
 

It has a button that says SAT and when I press it, it says "NO SAT" or something along that.
I want to subscribe to xm, if I did how would I get it into my car? Would I have to buy anything else?

you could buy the box that i have in my trunk....Haven't sold it because one day i might want a subscription.... oh the box is called xm tuner

Assuming your coupe was built after a certain date, it should be pre-wired for the SAT tuner. You just need to add the Nissan/Infiniti XM tuner and install it in the trunk. your dealer can get it.

Looky at what i just found

If you are interested i'll sell for 100 shipped

Or you can buy an aftermarket head unit and get navigation too. The new ones also can also stream pandora from your phone which is free.

soulglo i buy it

You can just use it by setting up a radio station for it to play the music through
but what i do for best quality is use the tape player to pplug into the xm radio and play the music through that. good quality from a dollar store tape player thing
