I just posted an update (12.0.21) that will be useful for some people.

For legacy WTP users wanting to use Expedition x64 for Navionics, you can now use Dfw2Exp to get data from Dfw. It is only a 32 bit app, so you need one of the 32 bit Expeditions installed too. Note that both installs should be the same version.

For users sending NMEA 2000 data and especially custom data to Garmin displays, there is now an automatic throttling mechanism when Exp detects high CAN loads. This only works for Actisense NGT-1/NGX-1 and Digital Yacht iKonvert gateways.

There are some nice updates to the AIS docking window.
