E125 Boat Position Display

[Ron.Ricci@1968.usna.com]

Thanks for the reply. The behavior was noted at different times with either the MFD internal or RS 130 selected for the GPS data source. Both have a clear view of the overhead skies. As reported in the original post, the position stopped updating and ended up about 1/4 mile off. The boat position display immediately displayed correctly when going from Chart to Home and back to the Chart screen. The frequency of occurrence is rare. The next time it occurs, I'll display the position on one of my I70's to see if that changes. This won't happen until next summer.
