If you own one of the newer Garmin GPS’s with a “spine” mount Garmin released official software via Webupdater that fixes several minor issues and promises to address the long standing inaccuracy with the Trip Odometer data field.

For those not familiar with the issue, most owners consistently report that the Trip Odometer records less than the actual distance traveled. This has plagued the Cartesio-based units in varying degrees since the Oregon x00 was released. Based on many tests I’ve found that the tracklogs, especially on the GPSMAP 62 and Oregon x50, provide reasonably accurate distance when compared to other GPSs like the 60csx and to test tracks which I’ve measured hundreds of times. However the trip odometer distance field always records short, sometimes by as much as 50% on slow (< 2mph) twisty hikes under dense tree cover.

I’ve upgraded all of my units to this release and haven’t seen any major new issues.  This weekend I’m hoping to get out and see if there is an improvement.  Let us know on the wiki forums (GPSMAP 62/78 | Oregon x50 | Oregon x00 | Dakota) if the fix is working for you!
