I went ahead and upgraded to 7.510 and still wasn't showing contours. I went into the Menu - Chart - Chart Select and my options are Auto, ContourXD, and Right or Left Slot depending on which slot I had my card in. I selected that "slot" and still nothing. In the same Menu under Chart there are two options lower called Base Layer and Overlay, if I set either of these from Default to AC, it then show's up, but the next time I use my other map cards (Navionics or Lakemaster) and switch back to my Autochart card, the settings revert and I have to turn Overlay or Base Layer back to AC. Seriously not sure why they wouldn't make it recognize the Autochart SD card just like it does my other two cards. At least I now have "Jigging Mode" with this firmware upgrade, whatever that is lol. I'll have to read up on it. Just curious, does anyone elses Autochart card show up in the Chart Select Menu? Rickie?
