E125 Boat Position Display

[Ron.Ricci@1968.usna.com]

My Raymarine system consists of:
• E125 MFD - V17.45-00403
• I70 (x4) – V3.05
• RS130 GPS – V2.20
• Ray 260 VHF – V2.030
• P70 – V3.05
• ACU-200 – V2.17 RSCP V1L4
• EV-1 – V2.17 RSCP V1L4
• Color HD Radar – V4.27 (not powered at time)

The boat position on the chart display stopped updating. The actual position was off by about 1/4 nm. The position source for the E125 was the internal GPS. The boat was following a route at the time of the incident. Zooming in/out and panning the chart display did not correct the problem. It was finally corrected by going back to the Home Screen and then to Chart Display. The boat position then displayed correctly and resumed updating.
I had noticed this behavior several times on an earlier version of the firmware (maybe V13 or V14) and never observed it on V15. This was reported on an earlier forum post which I can't find. I believe that on one of the times the problem was noted, the RS-130 was used for position input. This is the first time I have noted the problem on V17 of the firmware. The earlier occurrences were very infrequent.
