Try to rename the mapsettings.cfg file to mapettings.cf in your device's map's folder. If that didn't help, try this:
1. Save everything from the device, using Explorer (or Finder on Mac), include all the files (hidden as well). It is also known as a manual backup: http://uk.support.tomtom.com/app/answers/detail/a_id/13354/
2. Then format the internal storage (or memory card, depending which one you use) of your device. Use the COMPLETE format, not the quick. http://uk.support.tomtom.com/app/answers/detail/a_id/12412/
3. Go to TT HOME, Manage my "DEVICE", delete everything from the hard drive and try the update again. At this point you might have to disconnect the device a few times and switch it ON/OFF to enable it to setup some important stuff.
4. Copy your voices and post codes back to the device (also the maps if that didn't download either).
