Question about


ive been using the desire HD rom on my hd2 and am confused about navigation options present on the phone. In the programs menu i have maps, buzz, car panel, navigation, location.

Now i understand what buzz and maps is.
Now all the others are basically related to maps, but what is the function of location or navigation, i dont understand. i read somewhere that Location is basically pre-cached maps and i don't require a data plan for them? if yes when and how are the maps downloaded? is it through USB when phone is connected to PC or wifi?

If someone who understands these can please explain it would be nice.

Thanks. :)

Navigation is turn by turn directions for your phone. With maps you'd have to click next for each and every direction. Nav will read it out to you. It is not cached or stored, you still need a 3G connection for maps to work.
