The GPS manual that comes with the Victory Tourtech GPS (Garmin StreetPilot 2720) is dated December 2005.  An updated manual, dated March 2007, can be found online - here is one website that has it in PDF format http://www8.garmin.com/manuals/StreetPilot2720GPS_OwnersManual.pdf .

The manuals have the same number of pages.  The new manual adds a few items, reorders some instructions, and takes out a few diagrams.  The location of Garmin (Europe) Ltd is also changed from Romsey, UK, to Southampton, UK.
