DISP Options...

Just picked up myself a very nice Dark Blue 2012 Prius Three and LOVE IT! Now, I do have several questions.

1. On the DISPLAY options, its set for 2011 and I cannot figure out how to hold the button to reset to the correct date.
2. When I power the Prius off, and the display tells you what you've have driven and moneys spent, well it always says basic info, but I seen that theres a way to activate it to tell you have much money has been spent ever time from turned on to off...
3. The radio FM setting, there is a TAG button. Click on it, says it'll sync to my iPhone when plugged into my MAC next... Is that true and how does it exactly work...
4. Is there any way to program the new LED DRL to stay on when driving at night with the regular lights. If not, meh, not a big deal.
5. To get the best fuel consumption, is it best to daily drive with the ECO button selected?
