Raymarine continues to release updates to Lighthouse 3 on a fairly aggressive schedule. The latest is version 3.2 which includes support for three things I was very interested in – Navionics dock-to-dock autorouting, Fusion audio support, and upgrading other Raymarine devices. The update was released in late September 2017 and I have been using it for a bit over a month with a few issues.
In addition to the features above, the release includes a bunch of updates to sonar features, wireless streaming of Axiom to a TV or other device, C-MAP integration (which might be more important with the purchase of Navionics by Garmin) and more advanced map options. You can find out more details on all features on Raymarine’s support site.
