Sorry for the delay but I finally had access today to a decent internet connection and I was able to update the latest Navionics Hotmaps Platinum south mapping card. I tested the card in one of my HDS gen 3 9's and the card functioned properly including the satellite photo overlay prior to updating. After updating all 3 categories on the card, the card again tested good in one of my gen 3 9's. I want to thank navionics for following through and continuing to chase this problem for nearly 4 months. It appears that they now have a handle on it. If you have had the same problem with this chip, I would contact their technical support for a fix.
