Garmin has issued several new versions of firmware for the Zumo 550 and the latest version on the web site (which has major enhancements in usability and bug fixes) is v3.30. As you would expect from the numbering system, v3.00 was a major release with many important enhancements. However... the BMW-badged version of the Zumo is unable to make use of this firmware and is stuck in the dark ages with v2.10.
