Expedition Navigation Software / Navionics Will Not Activate

**Posted by JJ Flash** 6/15/2025 3:39 am

Hi, thanks for the discussion. I have the same problem with «no internet connection» reported from Navionics. I have also tried to cut out all firewalls, and other security programs with mi luck - so far.
Tricky this one!

The Expedition connection is setup as "default" and is working fine.

Navionics chart loaded is able to connect and grab chart updates etc. I have tried to activate Navionics both with the chart loader open and closed.

Windows firewall is disabled. I can't figure out anything that would or should be blocking outgoing connections. Perhaps I will have to dig in to the network deeper. Nick - any insight into an IP or URL this is trying to connect to so that I could test further?

Thanks!

Same issue, small box in the lower right corner - No Internet Connection. This is on home wifi while logged into Navionics Chart Installer

Exp doesn't have any influence on it.

It seems ok here. I updated an SD card here yesterday and it worked as expected.

The Navionics library was updated a few days ago.

Are these problems occurring with the Expedition 12.4.x or an earlier version?

When I confirm the Navionics installation by pushing "ok" in Expedition, I can see the program immediately us 0,1 Mbps network capacity just before the "no internett connection available" show up. I think this indicate that the problem is related to the Expedition software.

It is related to the Navionics system not seeing an internet connection - it is just an error message returned by Navionics.

Beyond that, I don't yet have any insights.

One useful thing to know is which verion(s) of Exp this is happening with as the Navionics dll was updated a few days ago.

It is all ok here. If someone with the problem could try an Expedition earlier than 12.4 and it works, that would help a lot.

I have just posted 12.4.2 as a couple of users needed new things.

This reverts to using the previous Navionics dll.

Apparently it solves the issue for those who have it, but if anyone else can confirm.

I wish I could try it but the laptop at issue for me is on the boat and I had to go out of town for a few weeks so hopefully someone else can try.

I had the same "No Internet connection available" issue yesterday when trying to install Navionics on 12.4.1.
Upgraded to 12.4.2 today and Navionics started working immediately without installing the cartridge again.
