A lot of the Entune system is fluff. But this is a very handy screen. Tells me the temp where I'm at for now, or what it will be like in a few hours, or the next three days. When stopped you can look at other cities.
I saw a report the other day that said, when you sale your vehicle, you need to have the entertainment system and everything you have stored in it, reprogammed back to factory specs. That way the next owner will not get your personal info.
