So if you switch back to the talk station, and hit the skip-back button, it just skips back to the point where you switched back to that channel. But as soon as you change the channel, that buffer is lost. If you have it on a talk station for a while without changing channels, you can skip back to the last chapter mark, which is usually a commercial.

Yeah, in all my other cars, that's exactly how it worked. Not sure how much value this functionality adds, but I'd much rather just have a persistent buffer with FF/Rew functionality. This behavior seems like it's downloading the buffer from the Internet when you hit the 'Start Over' button, so I guess this is part of 360L? And the skip limit seems to be something they've incorporated from the Pandora side. When I used the 5th skip, it said I had to wait an hour to skip again. I could skip forward or backwards to different songs, but it counted down the number of skips allowed from a max of 5. I hit the button and saw the same 'loading' screen before it changed to a random song. I switched to a Music station, and saw the same 'Start Over' button appear. Still no FF or Rew, but this might be of some use since the buffer doesn't seem to survive a channel change on talk stations.

It didn't skip back to the beginning of the show, but it also wasn't any part of the show that had played recently. When I hit that button, it said 'loading' for a bit and then started playing again, but I couldn't tell what part of the show it was playing. After driving around more, I noticed that a new 'Start Over' button appeared on the screen while I was listening to Stern. There's more to this SXM interface than I originally thought.
