I use Expedition on a boat with a newer Raymarine instrument system.
Laptop connection to the network is with Wifi.
This is the 4th year using it with this boat.
Have had very few issues to date.
We did replace the small mast mounted displays with some new larger units this past off season.
Otherwise, no changes to the boat or laptop/software.


This season, when trying to use Expedition, there are multiple data points that are not calculated or displayed.

COG, VMC, polar bsp, polar bsp%, target bsp, Mk Brg, Mk Range  are all showing "--"

When I look at the route, the range info to the marks looks correct, but the bearing to all marks shows 32767 degrees.

Any suggestions how to troubleshoot this would be appreciated.
