I can well imagine that you younger guys have all sorts of devises that will plug into the C-7, but for us older guys we might want to study up. Since the C-7 does not have a CD player you will need to find out what is needed to play our favorite tunes via a thumb drive, ipod, or other outboard source. Someone with a better background in such things will hopefully will see this thread and offer up some help and answer our questions on how to do that. I've been loading up music on a thumb drive for my music source and it has been fun putting on some "driving music" on it. Let's not talk about the tunes here. (I will start a different thread for that in the off topic forum) This thread is intended for folks to ask for help and find out about the sound system that GM has put in the new C-7.
