Hi there!
I'm new here and trying to update an XXL 540.
I have some experience messing with Garmin devices, but so far I'm having a lot of headaches with TomTom.
I've downloaded the maps from here and also read something about FastActivate, but I not sure how to proceed.
-Will I be able to restore everything if I do a Backup from Windows Explorer from every file in the GPS ?
- If I install maps from here, shouldn't I uninstall the maps in my GPS first?
Thanks for any advice you can give me !
