Hi all. I am in the very beginning stages of planning a one month trip from PE/EL to zambia, via Bots, around western side of Zim (avoiding Zim). - for August this year.
I have the android T4A app in my android headset in the vehicle, but must say that I have no experience in planning routes on this, and no knowledge of how to do this. I am prepared to spend money to get whatever is needed to allow me to browse maps, and plan the route, and perhaps also have a backup nav screen in the car once we are driving.
I would much appreciate experienced travellers advice here. If you could 'start again' with contemporary Southern Africa route planning, what hardware and what software would you use, and would you continue with the T4A software on the car nav unit.

Thanks in advance
