I just updated both of my 898's with the new 6.180 software. This is the first time I have had my units powered up on the kitchen table with no GPS puck attached. I noticed that in normal mode I have no "nav" or "chart" tabs in my main menu but I still have them in simulator mode. Is this just because a puck needs to be hooked up for these tabs to be available? Like I said, every other time I had a puck to attach to the unit but now the pucks are mounted on the boat so this is the first time with no puck hooked up. In simulator mode I have all of the tabs and all of the new features from the update. Thanks.
