If this is not the case I would try the map card in another Humminbird unit and try a different Navionics map card in your units.
hmmm--actually I had never updated the card since I got in earlier in the year. I tried the card in the 788 in both slots and neither would pic it up. I then tried it in my 597 and the same thing. I did update the card that evening--haven't had the chance to try it but if it doesn't work I will update it again and see what we get. It is the navionics hotmaps premium card---my fingers are crossed--paid 75 bucks to get the updates i'd hate to pay another 150 to get a new card--it did work when I first got it.
