hello All
Yes, you're right fredderf. my backup for Tomtom one XL was on my usb key but I lost it.
I have two Tomtom one is tomtom one 3 edition and the other is tomtom one XL.
On my TT one Xl I have a card sd with the navecore that you indicated to me recently.
But I no longer had the navcore and the card in the tomtom one Xl without this card sd (backup lost of my usb key)
so now i'm good thanks to you (and i gave you a thumb)
See you soon..
