So, guys I'm having a lot of problems here trying to find out what the difference is between the TomTom ONE 2nd Edition and the TomTom ONE 3rd Edition. I'm also having a lot of trouble confirming how the TomTom stores it's maps. If it's internal memory, how much is it. Whatever it is... What if a new map comes out that won't fit on the internal memory? Then what... I currently have a TomTom GO and want the TomTom One for it's smaller size. I'm also concerned which one has the latest maps, and if it doesn't have the latest maps whether or not it would be a free download since the device would be brand new. I think my biggest problem here is the difference between the 2nd and 3rd edition, and why the 3rd is $50 cheaper... And what memory it has.
