Thanks for posting. From those results, folk with versions of the GPS 18X LVC firmware 3.20 to 3.60 would be well advised to upgrade.

You may want to watch for several days. Previous 18x LVC firmware (3.60) drifted on my system from 0.5 to 1.4 seconds over a span of 6 days. I've been running a beta version of 3.70 for several weeks with no problems.

The new firmware for GPS 18x PC/LVC is also available: https://buy.garmin.com/shop/store/downloadsDetails.jsp?id=4055product=010-00321-51cID=170pID=223 Changes made from version 3.60 to 3.70: Improved NMEA output timing stability. Added support to enable/disable velocity threshold filtering. Modified the PGRMID sentence format for maintaining consistency with the other NMEA sentences.
