I've never seen anything so confusing in my whole life!! I can't read any of the posts I find until I have at least one post. (this one!!). I have a Mac so most of the software I find here is for PC.
Here is all that I need.
I have TomTom One XL. I'm not sure what version or size but it has an SD card slot. I live in Ontario Canada and want to upgrade to a new map. There has been a lot of road construction in our area with newer highways and street names. Any help would be appreciated.
