I have read this thread and some others. I have to admit I am confused. Could someone please tell me exactly what do i need to purchase to make a Macbook Pro display my position while flying TATL or TPAC? I basically want to replace the airline Moving Map/AirShow, etc. now that they have been turned of for "security" reasons. (apparently terrorists are unable to look out the window or read a watch)

What hardware, what software?

Additionally, is there any standalone unit that would do this?

Many thanks,
