Newbie Questions

I traded in a 2005 Prius with the navigation package on a new 2012 Prius Four with the Solar Moonroof. I really love it, but I'm finding the voice command very different from the old one, and there are a few questions I can't find an answer to in the owner's manual or the nav manual.

Is there some way to make the guidance less... chatty? I really don't need endless repetitions of "wait for the beep," etc. I get it. How do I shut it up? I promise to wait for the beep all by myself without prompting.

My old Prius had voice commands "suspend guidance" and "resume guidance" but I can't find anything similar in the new one. I really liked those commands because I could set the guidance up when I left town, pause it while I was in areas that I'm familiar with, and start it up again when needed.

When I ask it to find POI categories, is there a way to show icons on the map instead of listing them? That's what my old one did and that was way more convenient. I don't want to look at a list while I'm driving, or mess around with trying to find the right POI category.

How do I make a screen other this the map the default screen? Or, even better, how do I get it to just stay on the last screen I displayed? I've gone through the index in the manual and looked in what seemed to be the relevant places, but darned if I can find this.

Any help is appreciated! I took it for a nice long spin today and I really love it. But these few little things bugged me.
