I had a similar problem when my boat was in it's berth in the marina a few weeks ago.
In my case the instruments calculate TWA, TWD and TWS and feed it to Expedition.   However, the corresponding number boxes in Expedition did not display them.

It turned out that everything was fine!  
What happened that in the marina there were to few moving particles in the water to make the ultrasonic  speed sensor work.  As a result the BSP was not available and thus TWA, TWD and TWS could not be calculated by the instruments and this not displayed by Expedition.
An hour later all worked fine again as there were enough moving particles to trigger the speedo!

I'm very happy to see that Arome is now included in 11.15.20 !!
Would it be possible to also include the wind gusts?  It now only shows temp, wind strength and wind direction.
 

I have always wondered why the level of details you see on the map is related (fixed) to the zoom level (c-map in expedition, Navionics on my phone etc).
Isn't it possible to have two 'sliders':  1 to set the zoom level and 1 to set the level of detail being shown?  
Many times I like my maps to show a more zoomed-out view,  but I still want to see details (e.g. buoys).

Is this a limitation because of the way the chart data is available or is this something developers of apps (or expedition) need to implement? 
 

For an optimal routing to work you need a:
- "NAV" polar of your boat loaded 
- route with the first mark (start) selectd as the active mark
- wind grib file that covers the area of your route and at least the time period when you want to start.
- defined start time for the routing (Settings - Opt routing - start time).  Make sure the option "optimize for current position and time" is disabled.

Looks very good Nick.  Tnx!
