back up

[Guest mj82]

I want to hard reset my wizard as it keeps freezing, i have a backup made with spb from when i first had tomtom installed and configured which is the main thing i use, and need to know if after the hard reset if i run the back up from the sd card will it automatically reinstall these or do i need to use the tom tom disc again. Appoligies in advance if this is a silly question but i really don't want to mess up my device :D
