Customer Question

Hi,
I have a 78s purchased in 2011. I have recently updated the software. But I'm finding now that my supplemental maps (CNav North America, US g2 and Topo US - Texas) are not displaying. What might have gone wrong?
Thanks,
R Lewis

Hi there,

From the main menu, select Setup - Marine

Then select Marine Chart Mode and set it to Nautical or Fishing, depending on which microdisks you have installed.

Let me know if that works...

I tried that already. It had no effect.
Expert:  Pete replied 1 year ago.

Did the software fully update successfully, or was it interrupted or did it display any error messages at all?

Customer: replied 1 year ago.
it updated fully and confirmed.
Expert:  Pete replied 1 year ago.

Do you get an outline of the map or anything at all, or what do you see?

Customer: replied 1 year ago.
I have major highways with interstate numbers and a location icon. No details of any kind.
Customer: replied 1 year ago.
Previously. I had a great deal of map detail and color. Now it is nothing but a monochrome background with major roads.

Well, I've posted three responses with no reply's. Does that mean the conversation is over. I can't say it has done anything useful yet.
Expert:  Pete replied 1 year ago.

Sorry for the delay.

Let me see if the other experts have any idea on this.

Thank you for your patience.

Pete.
