GPS Navigation - Unknown Road

It's a little after 10:00 p.m. and we want to get home after a long day of volleyball matches.  Heather loads up the GPS and taps on current location in the start field and our hand-held tells us that we're on an unknown road.  After a few minutes it finds us and we're on our way.

Here are some of the things I'd like to see in the next version but doubt that they'll get implemented:

Turn-By-Turn.  As cool as the radiating little blue dot is on the purple road is, this is the most requested.  Touching the phone could be seen as texting and get you a ticket.  My friend got a warning so it does happen.  Version 3.0 maybe :)

Next waypoint signal.  This would let us know via some sound or vibration that we were approaching, and let me know the distance.  Maybe allow me set the distance.

Re-calculate route.  We missed our turn, or needed to stop somewhere off the route.  Let me get back on track.

ETA Display.  This would be for fun and the it would show based on our current speed what our ETA is.  Either setting average speed or actual would be nice.  A setting or toggle would suffice.   As it is, the display says something like, "1 hour 45 minutes with traffic."  "@78 mph: 1 hr 12 min."

What do you want to see?
