Hello. I just got my new Tom Tom GPS in the mail today and was getting it set up. I have the XXL 540M. I activated my lifetime maps download and as the download started it looked like the file was going to be too big with the current maps file on the GPS. Just prior to this I tried to download an update and I got an error saying there was not enough space for the new file. So I stopped the maps download and copied the maps file to my computer. I then deleted the maps file from the GPS and tried to download the new maps file. Well, it could not download it. It kept saying there were no new updates to download. I have tried everything to restore the maps file to no avail. I managed, in Windows Explorer to get the file copied back to GPS and after waiting more than a half hour for it to copy, when I tried to unzip the file it said there was not enough space on the device. I have tried everything to fix this and I'm afraid that I seriously screwed things up. It seemed that if I could easily copy a file to my computer that I could copy it back to the GPS just as easily. Whenever I go under the tab for files on my computer and I check off that file the only option I get it to delete the file from my computer. So, is there anything I can do to fix this or am I screwed?
