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.
I suppose it works nicely for the manufacturer that you can’t easily spoof the time for a GPS device :D
and I take it that also means the time of expiry has to exist in the firmware file.
can you please tell the version that does not have the anti-piracy for the echomap plus to roll back ?

You can only roll back the device to echomapplusmodel.
Garmin, how much is 30 pieces of silver for Judas today? Were they worthy for crucifix of GPSPower?
Can someone share the file GPSMAPSerieswithSDCard_20170825.exe
TNK! ...
Does any have or know where I can find the GPSMAP software update file from Aug 2017 (GPSMAPSerieswithSDCard_20170825)? The previous link provided is now dead and I need to do a software downgrade. The method has been very well documented in here (Thanks!!!), but I can't find the file for download anywhere.
