Kelid can do a portable navigator multi machine
As long as your memory card capacity enough, any navigator can do a multi machine.
My navigator turned out to be a way, I made a machine three figure.
You can add a small program, can achieve a multi machine, you need to put some of the map, look for a big card. Portable RAM is at most 128, more than the figure, the meaning is not very large, it may compare the card.
