I'm having trouble with the higher res navionics world map.

i downloaded and unzipped the file. I don't get a file, but a folder (Worldmap_4.0) with many subfolders

I put that folder in Expedition > navionics

I don't see the Worldmap_4.0_reduced file or folder in the navionics folder or sub folders - they are all empty.

I do have a world map in the program.., but when i put the new folder in the navionics folder and re-started expedition, it  was still the same world map
 

I found the Worldmap_4.0_reduced file in Program Files -> Expedition -> Navionics.

However I found no change in worldmap that I could see.  I tried putting it in both Program Files and Program Data to see, but no perceptible improvement in resolution,



 

okay - i was looking in program data, and that's where i put the new one.

now i have put it in program files > expedition, where i also see the reduced file - but no change in the world map.
 

previously, i had both the NT/Max and 4D versions installed.
will we now be able to have all  three installed?
 

if i have a subscription for navionics in their iphone app.., will that let me use the charts in expedition?

i think you get several installations with that subscription
 

Is this working now?
I am having trouble and was wondering if it's just me

i guess my problem is i have the B&G (airmar i guess) sensor, and it's highly non-linear

my 101.5% is good at about 7kts - but so good anywhere else

i am thinking of seeing if we can switch to a signet over the winter
