Hi, I got a XXL 540 for Christmas and I plugged it into my computer and down loaded Home, Anyways I went to put a voice onto it and and its saying there is no room on the gps and its brand new with nothing on it, So I went to manage gps and deleted the start up and shut down pictures to make room, and it wont connect or update or back up, Is there anything I can do to fix this?? I have dial up and a older computer, would this effect it?
