1. Yes, albeit I forgot how at the moment. Next time I'm in my car, I'll get it to display. But by then, I'm sure someone else will have answered.

2. "Display current location" is how you get it to pop up. Alternatively, you can click on the arrow that represents your car within the map screen at any time, and it too will pop up that same screen.

3. I have no idea about that, its not a feature I'm that interested in, so I wouldn't know. Sorry.

Hope this helps, some....
