I just purchased a 999 humminbird hd si on july 12th and i have a wisconsin / lakemaster card installed. The "Map offset command) is missing when the lakemaster card is installed. When i remove the card the command returns.
this system came with 7.46
This lakemaster card worked fine with map offset in my humminbird 798 si hd.
whats up with this?
today my map had me on top of an island and i went to use the map offset to correct and the command was not there.
Is there something wrong with this unit that it cannot read the lakemaster card and give me a map offset command?
