Changes made from version 2.20 to 2.30:

• Added German tide support.
• Made this product compatible with MarineUpdater for easier software updates.
• Added Greek language support.
• Added Icelandic grid support.
• Fixed Recommended Route line review problem where associated depth and/or description text was not being displayed.
• Fixed problem with Restore Factory Defaults function so that it now appropriately resets the sonar settings on a GSD-20 if there is one attached.
• Corrected problem with date displayed on the tide page for tide stations in the South Pacific.
• Corrected minor problem that prevented Daylight Savings Time detection from working properly in the Southern Hemisphere when rolling over to a new year.
• Fixed potential problem with displaying extremely high or low resolution BlueChart maps.
• Improved appearance of blue colors when the backlight is set to one of its two lower levels.
• Fixed problem with violet, blue and amber marine lights.

Changes made from version 2.10 to 2.20:

• Fixed a problem where underwater waypoints stored the current water temperature instead of the sonar history column's water temperature.
• Fixed a problem that could cause the Map page's 'digital data' fields to display improperly.
• Improved the tide chart interface. Now the tide chart uses a single time axis to display tide heights using your local time.
• Added foreign language translations for 'Submerged Wreck' and 'Underwater Rock'.
• Increased the maximum number of maps that can be displayed to 1050.
• Improved the track log reduction algorithm when navigating a track that contains 50 or fewer points.

• Fixed one-hour-early moonrise, sunrise, moonset, and moonrise predictions when looking one year or more into the future.
• Unit now displays a message when the active track log is full.
• Unit is no longer allowed to power-up with the minimum backlight setting. This prevents potential confusion as to whether the unit has powered on or not.
• Added Universal Time ( UTC ) format.

• Fixed problem with connecting a GPSMAP 172C to a GSD-20 remote sounder module.
• Fixed bug associated with doing a 'find' involving 'Marine Services'.
• Modified behavior of 'user card merge' feature to not overwrite waypoints of the same name unless the position of the waypoint is also the same. As an alternative, a unique waypoint with a slightly different name will be created.
• Corrected Daylight Savings Time problem with some Canadian tide calculations.
• Fixed various issues relating to user-card transfers.
• Changed the following BlueChart map labels:
  • 'Non-Dangerous Rock' is now 'Underwater Rock'
  • 'Submerged Wreck, Non-Dangerous' is now 'Submerged Wreck'
• Corrected Australian moon phase calculation errors.
