So, I recently found a ONE XL lying around in my house with vague memories of purchasing it in '08 or 9. So I decided that I'd like to use it; the first thing I did was install TomTom home, which notified me that I had to pay a ridiculous amount for maps that I can get from free anywhere that's not a dedicated GPS. So naturally, the first thing I googled was "ONE XL hack," which led me here. I've looked all around the site and can't find anything like an intro guide for noobs or something like that, glossary didn't help much. So, it'd be a great help if someone could direct me to the right thread or answer these questions:
What is possible with my device (that TomTom doesn't want me doing?)
What should be the first things I do, what do they do and how do I go about doing them?
Thanks for the help!
