Dont know if will are a bad news but just install in ECHOMAP PLUS 92sv Firmware 7.50 a Third party >IMG map generated in [Only registered and activated users can see links. ] and it works (many terrestrial info but not so much sea info, its very interested for lake navigation that are my case) , after install just advice that the map expire in 8 Feb 2019 40 days after installation.
Its only 40 days of working map, after try a backup reset and reinstall to see what happens.
