Navionics card freezing up my helix 9
Anyone have any idea why my Navionics card causes my Helix 9 DI gen 2 freeze up every time its installed.. unit wont turn off or on if card is installed, have tried putting it in when unit is powered up and when unit is off then install card and turn on either way it freezes up.. it does not do this when installed in my Lowrance HDS 7 gen 2 touch screen.

Here's what the book says: it says the unit should recognize the card automatically but I don't think mine did.
