Garmin Colorado 400t 2.90 Firmware Update

By | February 22, 2009

garmin I decided to run the Garmin WebUpdater on all of my GPS units this weekend to see if I was still current, but nope, I wasn’t.  I was running version 2.80 firmware on my Garmin Colorado 400t, but it looks like Garmin released a much anticipated version 2.90 of its firmware.  The 2.90 firmware was released December 5, 2008.  Units with versions 2.70 and 2.80 have been well known for their tracking errors (see the GPS Tracklog), but the change history doesn’t say anything about fixing issues like this.  Here is what Garmin claims was updated:

Changes made from version 2.80 to 2.90:

  • Added support for Garmin GB Discoverer maps
  • Added ability to view marine chart notes for marine points
  • Added ability to change the date for the tide and currents charts
  • Added support for marine fishing, nautical, and off modes
  • Fixed a potential shutdown that can occur when panning the map that is showing satellite imagery
  • Fixed issue with 3d view not showing proper elevation detail
