Great for Mexico

This apps pro version includes terrain data for Mexico! I looked for this for months. In the route planning mode you get a cross section of the route with altitudes - very useful for planning trips in the mountains. Inflight you see the terrain altitudes for the next 9.4 nm - a great safety enhancement.

Great app. Just need to allow us to put instruments next to the artificial horizon.
