    LOWRANCE NETWORK NOT SHARING NAVIONICS CHARTS

    Hello I've two each Lowrance HDS 12 Live units networked on my boat. The console HDS 12 unit has the Navionics card installed in it with a C Map card also. They are both connected to the NEMA 2000 and also connected together with the Ethernet cable. My console unit displays the Navionics chart no problem but it will not display the Navionics chart on the bow mounted HDS 12 unit. Anyone else have a problem like this before please advise thanks

    Usually a bad Ethernet cable, common issue.

    Possibilities include:
    Both HDS LIVE units must be on the same version of software updates.
    Bad ethernet cable.
    Bad card slot. Try moving your Navionics card to a different slot, including up to the bow unit and see if problem continues.
    ciao,

    Also please list all components of your system. Any modules? How exactly are the units connected?

    Are you able to share th C-Map card? If so then it is a Navionics issue. If not then it is an ethernet cable issue.
