Before the 8.0 update I used the steering wheel right scroll button to choose my audio source. It was very easy and allowed me to keep my eyes on the road while switching from slacker to xm or whatever. That functionality appears to be gone. I could use the main touch screen, but that requires me to take my eyes off the road for longer than I would like. What do you all do to switch audio source? Is there another shortcut somewhere that I could use? Thanks for your tips!
