Colorado 400t, Software Ver. 2.80 in GPS technology and devices Posted November 18, 2008 Here's a list of the changes: Changes made from version 2.70 to 2.80: * Fixed issue when marking waypoints in the W Malayan RSO position format. * Added GDA94 and NAD83 datum support. * Fixed importing gpx files from outside of the Garmin\GPX folder. They did fix the background colour issue with CNNA NT 2009...... So they obviously don't list every change/fix they make in these updates. It would seem then that one needs to check out their particular issue with each update to see if it's been fixed, rather than relying on the list given.
