I just went to YouTube and found several videos pertaining to that unit. I endured the same learning curve with a different unit so I understand your frustration. Watch a few of those and you’ll find one that you like better than the others. Just don’t try to learn it all at once. Get a little info about one or two certain things and use them til you understand those and move on to the next. Mine still does things that I have no idea about but it also does what I need it to and that’s what matters. Good luck with it, hope this helps.
