hey guys, i tried searching but couldnt come up with any answers... how do i go about erasing all the data from the unit? i am selling mine and want everything returned back to factory settings and all my information like stored locations, phone numbers and so on erased... thanks for your help

i would aslo like to know? How do i reinstal 3.02 the new update again if i already have it installed?

so i found it, it's in the manual, while the unit is starting up, press and hold the map button, then the screen will come up that will let you erase everything

erase it to what?
