Wärtsilä has taken the decision to withdraw the WMS service (which iRegatta uses to get the maps) as a commercial product.
This means that you no longer can start new subscription or renew existing subscriptions of Wärtsilä maps in iRegatta, iRegatta Pro nor iRegatta2.
For those who have existing subscriptions, Wärtsilä will still keep the content available for the rest of existing subscription time, and will strive to come with additional information before October, about future plans.
If you are using the Wärtsilä maps, make sure to turn on caching. That way maps are stored locally on your device, and you will be able to access them for the remaining subscription period, even if the Wärtsilä service should be temporary unavailable.
In iRegatta2 Navionics is an alternative solution, and I'm working on getting this available in iRegatta/iRegatta Pro as well shortly.
