When i want to upgrade my TomTom XL, i get an errormessage with not enough space on the unit.
I have taken backup through TomTomHome + the way it is described in the forum with showing hidden files, and copy all content to a safe location.
The question:
Should i format (delete) all content on the unit before running the installation process?
If yes, how is this done? simply mark all files and press delete?
Looking forward to hear back
