January 25, 201511 yr Hi Glenn, Well this is getting weird. My Navigraph was outdated so I updated to the latest (1501). Still couldn't load ANTAK into the 750. Now the weird part. The GTN750 does not use Navigraph, so that is not it. When it powers up, what navdata date does it show? Bert
January 26, 201511 yr Bert, How do I get an update? I just re-downloaded and installed the latest version (1.06). Still have the same problem. Jim
