If you have booked a hire car, before you travel we recommend downloading maps from Osmand (http://osmand.net).
They use maps from Openstreet https://www.openstreetmap.org/#map=14/23.1030/- 82.3533 and you can use them offline. This will be beneficial in Cuba due to the problems with using internet. If you are worried about navigating your way around Cuba or would like more information, please talk to us.
We advise against using live satellite connections. See our related post on internet access costs and limitation in Cuba. Use offline maps instead, even if less accurate than the real thing, to avoid hefty telephone bills once you return.
