If you're thinking of getting these for business then I've found a gps tracker mode on the software for the maps, and when I clicked on it a message saying no hardware available came up.. I'm gonna enquire about this and then find out if I can track each individual unit.. I've got four now at work for some of the other drivers that wanted them and I've programmed all their maps and data cards on my laptop... Sneaky Sneaky can see just what they are upto But also if any "Go Missing" I'll be able to track them forever as soon as they are turned on.. :winky:
