It is even worse than that. Yes, if you upgrade it will delete any New Zealand
or Austrailia chart info that you have already downloaded and will not let you view charts
from that area. But they go further. Even if you do not upgrade, it won't let you download charts
from those countries.
I think it is theft.
You paid for the right to download some charts and now, after the fact, after taking your money
, and refusing to refund any, they take away that right that you paid for.
I can't believe they are doing this. Who would ever trust them to in the future if you can't count on being able to download the charts you've purchased? If I went around selling some kind of option, then told people later that it was too costly to actually give them what they paid for, I'd be put in jail for fraud!
Here's another problem with Navionics. You don't have a list of charts that you've purchased, or a list of charts that you've downloaded. This makes if very difficult to plan in advance for long trips (like a run through the South Pacific). You have no way to compare against a list of paper charts. And, you have no way to select charts to delete from memory after you've used them to free up memory. For those who don't know, when you are looking at navionics charts on the iPad or iPhone
you might just be pulling them down from the internet
and if you sail out of WiFi
or cellular connection, no more chart - unless you downloaded it. So, a list of what is downloaded is critical unless you don't care that you might have been mistaken in thinking you downloaded a chart of the atoll you want to visit and not know that till you get there.
