Very odd.. My Garmin pucks did NMEA right out of the box. They also had the old (2 years ago) firmware that "lost" a second right around XMAS/New Years. I updated them. Puck-ing things!

I've seen lots of guys on sailing email lists get bit by the same thing when interfacing instruments to Garmin. Good luck. Bob, WB3AWJ Allstar 27784 Randy Neals <randy@neals.ca> wrote: That was it! I downloaded the Garmin config program.Updated the software on the GPS 18X LVCConfigured it for NMEA output.And now it works, no error messages. The Garmin protocol looks similar to NMEA so I didn't catch that there was a difference. Thanks Robert! Randy W3RWN / VE3RWN On Thu, Jun 13, 2013 at 6:55 AM, Robert a.
