This is our 2nd road to Hana trip and the app is excellent. We used the other cd on our first trip a few years ago (also an a+) but this app kept us right on track and knows exactly where u r and updates u with info at the exact time u get to a spot. Not as funny as the other one and no music but definitely a must have as u can depend on it to keep u on track and it gives u great info and history I highly recommend!
