Jim Hamm has another interesting bit of info here: "For travel there is an app for your iPhone or iPad that is free today: Maps.Me. In this app you can download maps of the various states ( or even around the world) which you can use when you're offline. Normally the cost is $5 for this app. You might take a look and download it from the App Store." https://itunes.apple.com/us/app/maps.me-pro-offline-maps/id510623322?mt=8
