Why are you making up this kind of statement when you clearly don't
have any proof of this. I suspect that he's most likely feeding
garbage to the chartplotter and it won't/can't draw the chart,
leading to the blanking. I can easily imagine this happening if the
lat/long is changing too rapidly for the system to redraw. When the
lat/long changes slowly enough, that's when he sees his position jump.
You can't expect to feed garbage to a system and have it behave
"correctly" when the lat/long change delta exceeds anything reasonable.

He's not in court, yet, so we don't have to "prove" anything to you or
anyone.

Any REASONABLE system would WARN you that it is receiving "garbage" with
some kind of error message on the BLANK SCREENS....instead of just
leaving you there, in the dark, wondering if you're gonna run over a
rock or bouy....

How slow is slow enough for it to render the chart? 5 seconds? 30? a
minute?

There's gotta be some kind of ERROR - WARNING timeout, right? I didn't
see one in the video, just a blank screen saying nothing....

How many systems are out there that wouldn't display an error message? I'd
guess that most vendor's systems wouldn't, as they expect the data to be
correct. What do you think your RL70 would do if it got bad data? Or a
Garmin? Probably the same thing. Expecting the developers to add in code
to check for rare events like this just doesn't happen. They have higher
priority functions to implement.

In my opinion, RayMarine isn't the bad guy here. I think that there's a
very high probability that he has something mis-configured in his system.
Your guess that it's the positioning of the GPS antenna seems reasonable,
especially when you look at the photos of the radar arch and GPS mushroom.
This should be easy to determine by running the system and turning the
radar on and off.

Since it appears that he installed the system by himself and hasn't
obtained professional help, RayMarine seems to have done everything that
they should have, and probably more.
