How do we save maps to dongle and how do you load different maps Also i was told it holds 4 maps is this true

 

yes it is true it holds four maps. to save and load maps..go the screen that says "Mircotech LT***"..move to the right and you'll see screens saving and loading the maps..4 each... to save or load..just hold down the programming button until you see it saying it says saving or programming and when its finished it will say programing passed.
