Hello everyone, I am delighted with this forum. I have learned a lot and today I finally registered.

I have a problem with reading nautical charts in the garmin gpsmap 722. I have updated the GPS to the latest version (11.00) and I do not recognize the nautical card "pirate".

I downloaded the version GPSMAPSerieswithSDCard_20170825, since it is the latest version that supports the "piracy" of nautical charts (v8.80)

When I perform the "downgrade" I keep getting the version (11.00) and I have not done the "downgrade"

What I can do?


Greetings and many thanks
