Did you find the driver for your serial to USB cable?
As for downloading maps for Oziexplorer I have gotten plenty via torrents but if you're having internet issues then that won't help you. Did you mention recently that you're still on dial-up? If so then forget torrents.
If you still need a driver for your serial to USB cable then PM me your email address and I'll send you the driver for mine. It might work. Especially if you bought your cable through Jaycar or Electus.
If you want some maps then include your postal address in the PM as I have one or two
