help with back up plz

[kna]

hi all

just got the ttg300 i plug in the usb and turned the tt on.
opened my computer and clicked the tt file.
it starts up the cd then i tick backup/restore settings then back up settings to pc.
then all i get is this Please connect the power supply to your TomTom GO and switch ON your TomTom GO.
Next, make sure that your TomTom GO is connected to your computer, and then press the right button below.
Press the left button below to return to the Setup menu. i press right button and it just comes back to that message
so do i need mains charger to continue the set up.? is that why i cant see gb maps any where even when i copy and paste to my pc .?
i had to quit that but i did register on line first
then i tried to back up the tt sd card by opening my computer there is a file not a folder called tomtom (D: )
i right clicked it then copy and paste in to a folder in my documents
i checked the properties for the tt file in my computer it is 76.6mb used none free
i also checked the properties of the back up file i made its size is 71.4mb/size on disk 85.8mb
contains 5,798 files and 105 folders
am i thick or does any of this make sense shouldn't the tomtom (D: ) be 128mb total size with over 100mb used and my back up folder should be over 100mb
any help would be really great

btw it works fine i just want to make a back up on my pc ready to put on a new card before i add speed cam data

thanks and great site btw
