Changes made from version 3.60 to 3.70:
- Corrected a lock-up problem caused by satellites using non-sequential iono bands.
Changes made from version 3.50 to 3.60:
- Modified 'Place of Worship' and 'cemetery' symbols.
- Changed Austrian datum transformation parameters to dx = 594, dy = 84, & dz = 471.
- Fixed problem with potential shutdown when using very old Almanac data.
- Corrected problem with Australian celestial moon phase calculations.

Changes made from version 3.40 to 3.50:
- Fixed potential memory-corruption problem that could occur when tracking more than one WAAS satellite simultaneously.
- Improvement to prevent delays when using differential GPS.
Changes made from version 3.30 to 3.40:
- Fixed a problem that could cause the product to take much longer than expected to determine its internal temperature.
Changes made from version 3.20 to 3.30:
- Added new translations for the French language.
- Improved WAAS/EGNOS satellite selection algorithm to select the satellite with the most beneficial corrections given the unit's current position. A unit will not use a WAAS/EGNOS satellite if the unit's current position is outside of a given WAAS/EGNOS satellite's service volume.
- Fixed a problem that caused the NMEA GPGSV sentence to not be compliant with the NMEA 0183 v3.01 Standard.
Changes made from version 3.10 to 3.20:
- Added Croatian map datum.
- Fixed datum selection fault in software version 3.10.
Changes made from version 3.02 to 3.10:
- Implemented position Auto Averaging support.
- 'Track Log Full' message is now displayed when the Track Recording Mode is
set to 'Fill' and there is no more space left to record track points.
- Added new metric version of Nautical units that underflows distance
measurements to meters instead of feet.
- Elevation units no longer overflow to a larger unit of measure when the value
gets large. For example, if you are using Statute units and your elevation
rolls over from 999 ft to 1000 ft, the unit will now display 1000 ft rather than 1.0 kft.
Changes made from version 3.01 to 3.02:
- Improved EPE calculations when using WAAS.
- Corrected differential status message bug that occurred when using the 'Other DGPS' communications format.
- Modified waypoint review page to display maximum depth when entered depth is greater than maximum allowed.
- TracBack route renaming is no longer allowed.
Changes made from version 3.00 to 3.01:
- Added support for handling input of NMEA DBT depth sentence.
- Implemented new Advanced NMEA setup item for setting the Waypoint ID output format. This should allow for backwards compatibility with a wider range of NMEA driven products, including some older AutoPilots.
- Corrected possible highway page lockup bug.
- Corrected 'Light' string translation for Danish language so that it now properly indicates reference to the unit's backlight.
- Improved Store Demonstration Mode behavior for language selection and backlight level settings.
- Removed general hotel reservation phone number from Metro Guide data review pages, as the number is no longer valid.
- Fixed an error that prevented the Arrival alarm from re-triggering during a Go To operation if the distance option was selected and the distance value was changed.
- Corrected the drawing of the horizontal route line that used to be strangely vertical drawn when the view is zoomed to 20ft.
- Corrected the case usage in map setup page.
- Corrected the anchor drag alarm so that it will go off again after leaving the alarm circle then coming back in.
- Corrected the possible lockup bug in backlight in Disclaimer page.
- Corrected the set year page forces the year to 2000 if year less than 2000 is entered.
- Corrected the map so that it won't have expiring unlocks.
Changes made from version 2.02 to 3.00:
- Allow individual classes of NMEA sentences to be enabled and disabled.
- Added support for GPBWC, GPXTE and GPVTG NMEA sentences.
- Added 'Point to on Map Page' option to map-based map feature review page.
- Pressing the 'Left' or 'Right' cursor keys in most lists now scrolls the list a page at a time.
- Improve collection of WAAS data when tracking more than one WAAS satellite.
- Fixed possible lockup when calculating sun/moon rise and set times for extreme latitudes.
- When editing a non-active route on the map, don't automatically initiate navigation of that route.
- Added RT-90 Grid.
- Improved appearance of directional pointer data field.
- Fixed TracBack point review page problem that caused an invalid position to be displayed.
- Corrected differential status text discrepancy between GPS page and Com page.
- Reduced the amount of path smoothing done when saving tracks.
- Changed skyview moon on celestial page from crescent shape to a half-moon shape to avoid confusion that the skyview is trying to show the actual moon phase.
- Fixed GPS page Signal-to-Noise Ratio update problem that occurred if the unit was receiving RTCM signal while the protocol was switched from RTCM to some other protocol not supporting RTCM.
- Added support for RTCM In/NMEA Out serial data format.
- Changed 'Serial #' to 'Unit ID' on System Information page.
- User waypoint depth is now always initialized to invalid instead of 0.0 if a valid depth is not being received via NMEA input.
- Some position grids now have a fixed map datum associated with them, meaning the user cannot configure the map datum when some grids are selected.
- Corrected the use of magnetic variation in the GPBOD (application to bearing) and GPRMB NMEA output sentences so that the Auto Mag Var Value is used unless the unit is set to User Mag Var, in which case it should use the user's value.
- Improved responsiveness of GPS positioning in shaded conditions.
- Changed both Swedish and new RT-90 grid text outputs to display the northing on top and the easting on bottom, which is reversed from the way it was previously displayed. Also, 'X' and 'Y' are now used to indicate northing and easting instead of 'N' and 'O' respectively.
Changes made from version 2.01 to 2.02:
- Fixed line drawing problem associated with map-based distance measurement utility.
- Improved speed and reliability of AutoLocate operation.
- Added power-on GPS Information popup page.
- Removed 'Stop Navigation' confirmation message.
- Daylight Savings Time is now taken into effect in tide computations.
- The COM 2 NMEA Input problem has been fixed. This was caused by not properly detecting that the interface for COM 1 had been set to a value that allowed NMEA input on COM 2.
- Improved TracBack waypoint name generation.
- Added poor coverage icon display at power-up, to be used as an indication of when a valid fix has been obtained.
- A Loran TD conversion problem has been fixed.
- Corrected Man Overboard waypoint symbol colors.
- Updated configurable field 'Off Course' indicator to include left (L) and right (R) indicator.
- An improvement was made on the highway page, such that Route and Destinations waypoints are now always drawn on top of non-navigation related waypoints.
- Map settings now stored in nonvolatile memory when the map setup page is closed to ensure that any changed settings aren't lost if power is interrupted.
- Implemented a timeout that causes the map popup window containing the scanned item's name to close.
- 'Go From' navigation point is now being stored in nonvolatile memory in order to ensure that it isn't lost if there is an unexpected power interruption.
- Incorporated a map refresh after transitioning from one active route leg to the next.
- Fixed rounding errors that occurred when storing active track points.
- New user waypoints are now created with invalid depth instead of a value of 0 (zero).
- Change the name of the existing 'Hu-Tzu-Shan' map datum to 'Taiwan'. Added a new datum entry named 'Hu-Tzu-Shan' which conforms to the published Taiwan map datum definition.
- Added ability to Start/Stop the Simulator from the GPS Info Page.
- Added International and United States versions of the Diver Down user waypoint symbol. The pre-existing Diver Down symbol is now named Man Overboard.
- Improvements were made to the following Tide-related features:
- Don't display charts with Tide data that has excessive error.
