I was wondering if there are any software updates for the entertainment systems for the 2015 Suburban. I drove a 2016 the other day and noticed various differences between the 2. One of the differences that I noticed (which I find annoying) is that on my '15 it is a pain in the ass to change stations. You have to press menu, then hit a button, then change the station...or use the steering wheel controls. There is no easy way to change stations. With the '16, the presets are displayed on screen. Am i missing something (a setting maybe) on my '15 or is it the way they work?
