i have been using and patching an old tomtom one v2 with good success for a while now.
I am currently in the process of buying a second handn 520t i understand it has bulit in maps etc and also an sd card slot.
My question is can i run navore and maps seperatly from the inbuilt navcore etc ?
i want truck maps and older navcore for when im towing them swap the card and use a newew latest navcore and latest car maps when not towing can this be done ?
