Excellent advice H2O. I should add also the interface on the C3 really is not any harder than using a computer web browser. Seriously if you can do that then it should be a cinch.
tapping say a forward arrow area will instantly forward , or hitting it and holding it down simply fast forwards through the tracks until you take your finger off the touchscreen area in question. same with scrolling through the folders= the return arrow is simply much the same as a "GO BACK" button on a web browser. Not much more than say a 5-10 minute learning curve. I was a a little worried at first , but it was really intuitive to be honest for me. SO much now that even going back to it after a while it takes little if any thought to "get it" again.
Add a BH and it bumps it up another notch. I mean look at it there...just perfect like they were meant for each other.
