I noticed that when changing Sirius channels using the steering wheel controls works a little strangely now. I'm not sure if it was always like this, but holding the button scrolls through channels 5 at a time. That's a cool feature that I don't mind...but if you click too fast to just go down one channel or two, the stupid thing suddenly goes 5 or 10 channels. Even if the 5 at a time feature was already there, I feel like the sensitivity was somehow tweaked, to the point where the switch is damn near useless.
Any other ideas what else has been messed with?
