I'd like to reset the D1 back to how it was when it came from the factory - there are a lot of problems with the used D1 i just bought, for example, in Nav, i cant set a new destination, only 'return home' and i cant even change settings when i click the settings tab under the navigation main menu. so i hoping this will fix it.
how do i master reset the entire d1
p.s. i searched
EDIT or tell me how to make it so i can do an address search - right now its greyed out and i cant do anyhting but 'return home'
