HELP ME PLEASE!!!

I was driving today, and after listening to XM radio for about 3 min it cut out. I was listening to MLB on XM and the brodcast just went out. It was strange so I turned it off, I tried turning it back on and no luck. I turned off the car, no luck with it coming back on when the car was turned back on. I don't know what fuse to check, I hope that's the issue. The voice command buttons on the stearing wheel dosen't work either. Non of the buttons under the nav work, not even the radio button. Any guidance would be great. I am worried, don't have warrenty on the vehicle because it ran out. It's an 04 TL with 105,100 Miles on it.

Thanks

 

that happen to me about 2 years ago, but i brought it to the dealers and the warrenty cover it. u can try bringing it to the dealers to check wut is wrong first
