If not, get to the page from
www.tomtom.com via FAQ or Support?
As soon as you get your TomTom working, connect it to your PC using TT Home
and start Windows Explorer (a quick way of doing this is to hold down the
"Windows" key, normally second from left on bottom row of keyboard, and
press the letter "e" (no quote marks). Then create a new folder (in
Windows Explorer click highlight your hard disk (usually Local Disk (C

,
click "File" (top left),"New", "Folder" then enter a name (such as TT
Backup). Next, highlight the TomTom folder (something like "E:\TomTom
720" - it all depends upon what name TomTom used, but should be easy to
locate), hold down the Control (Ctrl) key, bottom left) and press "c"
(copy), highlight the new folder you just created on your PC (TT Backup)
then hold down the control key and press "v" (paste). This copies your
ENTIRE TT to the backup folder on your PC so that you can always get back to
a working TT by copying the entire contents of your backup folder back to
your TT root "E:\TomTom 720"? - TomTom Home does NOT create a complete
backup of a TomTom (so is useless).
