I have an HD Ultra map card that I use in my Echomap 70s. It was updated to the newest
version 2017.01. It works great in my Echomap 70s but when I put it in my Echomap 94sv
I get an error message" Can not unlock map" when it is trying to load them. I tried removing the
.hml file it creates when installed. Still not working but it did recreate the .hml file. Any help appreciated.
If not I will just have to call Customer Support on Tuesday.
