Sirius 34 and 36. Every now and again i will venture to other channels but it is rare.
I lucked out and bought a lifetime subscription when it was $400 back in 2007. I love the fact that even driving cross country i only have to turn the volume up or down.
i do believe though that the music quality and range has gone down since the merger with XM.
I was looking into the lifetime but discovered it is only a lifetime for the life of the radio/receiver. The last few I have had only lasted about a year before it busted.
