Does anybody know how to get an updated GPS DVD for the 2010 Toyota Prius? This thing is currently worthless... it doesn't recognize the majority of streets around my area. I have no idea if Toyota even cares enough about their customers to update their map with new information. Plus, not that an updated map can fix this, but it ALWAYS gives the worst directions possible... taking me faaar out of the way to get on some highway or some road that it considers "better", when the REAL route is soooo much closer and easier. The Maps app on my $199 iPhone is VASTLY SUPERIOR (not even close) to the GPS navigational system in my $30,000 Prius. Too bad Apple doesn't make a car. Toyota should be ashamed of themselves.
