Re: Caribbean charts
Yes - the charts are in the new format and did work on one install of expedition. I didn't verify a second install. Please let me know if you succeed on the second install.

Re: Caribbean charts
Today I purchased the NV 12.2 charts at a retailer near my home and I also downloaded the same charts from the NV website. Using the product key included in the kit of paper charts, I successfully installed the downloaded charts on two Windows PCs (my desktop at the house and my boat-to-boat laptop) and Expedition now uses those charts without issues.

Re: Caribbean charts
great - thanks for the info.
has anyone compared the NV charts with the C-Map? I have an older (~6 years) C-Map for that region installed on expedition now on my laptop.
Do you like one better than the other for this region?
my panasonic toughpad tablet has no charts and i was mostly getting the NV charts for that.., but i guess i could get another newer C-map license.

What's odd is that I purchased the same charts last year through iNavX and they downloaded directly into my app and were much cheaper.
I think that if you get them through iNavX they are $59 vs $79 if you buy the chart book, but the iNavX purchase is a subscription for 1 year, you can only use them in iNavX, and i think you don't get a chart book.
So the chart book is a better deal - you get 5 installations, the license lasts forever, and you get the paper charts. The only problem is that it looks like inavx can not be one of your 5 installations - if you want to use your charts on an iphone or ipad, you have to use the NV app - for me it will just be a backup, so i guess that's okay

Re: Caribbean charts
I am glad i bought the NV charts - as I found a problem with my installed C-map charts
The Island of Redonda, which is a mark of the course in the C-600 is incorrectly located in C-map
This is because in sourcing the chart data for Redonda, C-map only used the 1:500,000 and not the 1:90,000 chart data
So, as is common, on small scale charts - features are not precisely located on the 1:500,000 scale chart.., because you are supposed to use large scale charts for detailed navigation. The problem with the C-map charts is that as you zoom in on redonda, you never get a larger scale chart, because they didn't digitize it for redonda
i have attached links to three images
the first shows the location of redonda in C-map - at all zoom levels- (with a racenote around it) and another race note showing the actual location from NV charts 1:90,000
the next image is the NV charts 1:500,000 which shows the location of Redonda used by C-map for all zoom levels - they agree.
the next chart shows the location of Redonda on the 1:90,000 NV chart - the level that C-map failed to include. You can also see a racenote showing the only location of Rdeonda in the C-map
edit - well it looks like the image thing isn't working, but if you copy and pase the url you can see the images
