I use a laptop for my maps when I travel.
The GPS is a Garmin Etrex (app £90) this tracks the satellites and gives me my position on the laptop, this enables me to see; where I am, and where I want to go. In UK and europe I use Microsoft Autoroute Express, and in Africa, Fugawi World Explorer, which has a world map, and I buy the Geo Ref'd maps from Darr as they have many areas of the world covered. Obviously the laptop has many other uses, and the Etrex can go with you when you leave the car to remind you where you parked it.
