Hello,

I've got a 5800T in an RV-10. I keep the software and subscription data up-to-date on each cycle. I noticed, starting 2 cycles ago, that many of the geo-referenced plates pulled from Seattle Avionics no longer properly geo-reference the aircraft on the plate. Most of the time, the position indicator appears somewhere on the chart, but never moves in relation to the aircraft position. We see it with both approach plates and airport diagrams. What is interesting is that the aircraft indicator will rotate to correctly indicate the GPS track of the aircraft, but not the actual position.

What could be the cause of this?

Thanks!
Russ
