Hate to be the one to point you to this:

Under the "Requirements" tab, of all places, is "Terms & Limitations" which begins:

If you purchase a nüMaps Lifetime subscription (sold separately or bundled together with certain GPS models), you will receive up to 4 map data updates per year, when and as such updates are made available on Garmin’s website, for 1 compatible Garmin product until your product’s useful life expires or Garmin no longer receives map data from its third party supplier, whichever is shorter......... blah, blah... So they have a legal out if they are no longer receiving map date from Sensis. Let's see what they do with the "nuMaps guarantee" for devices sold with Sensis 2013.10 after the release of Navteq 2013.20 too ....
