I read in the v2.6 release notes that:
the ability to read GPS (location, height, speed) from the N2K network has been added.
I can't get this working with my CCGX running v2.66. It can see the other devices on my n2k network. I unplugged my USB GPS and rebooted.
Any tips on where to look or if there are any configuration options that need to be set? I couldn't find any.
