You can also use Active Captain offline when you are not on the boat. Editing waypoints on AC will be easier to do than standing in front of the 1242 when it is installed in the boat. I loaded Active Captain on an old iPad Mini that I had laying around. If I were taking my boat South on its own bottom I would want to build that route, use it for the trip and save it off. When I build my waypoints for an artificial reef its easier to do on my laptop in my living room. With 300 waypoints for NJ and 300 waypoints for FL I don't want them in the machine at the same time. They are MAC HomePort users managing multiple lists of waypoints for different reasons. Your situation is a little different than others I have talked to on The Hull Truth. It does not give steps for transfer over Garmin Network but I assume you just choose the SD card in the other unit? Its a testament to how good it was that we still want to use it now. ( even the idea of still using 32gb SD cards is like keeping one foot in the past) At some point you can't keep dummying down new stuff to keep old stuff compatible. I understand that wifi and active captain is the future. I'm still not sure how Active Captain will help us with the 4200 series since it does not have wifi and doesn't support active captain. I have done this before, putting them into an EchoMap94. Clean up waypoint names and such and then export them to a. This weekend I'm going to try getting my waypoints out of the 4208 (.adm file) and into Homeport on a PC laptop. Garmin's current software suite of Express, Homeport, MapManager, MapInstall are all there to sell charts.

I replaced mine with a 32gb card - doing it now instead of later when its filled up! Only pain is the card slots are on the back of the unit but you can buy extenders to put the slots somewhere else. My unit has two micro-SD card slots one of which had a 8gb card that is used for extra storage for downloaded maps, Active Captain and Quick Draw. I have been able to transfer my HomePort waypoint sets to and from my 943xsv. The good news is the new units that support Active Captain also have the same Manage Card functions the old units have.

HomePort only supports g2 maps which are no longer available. If you want to run HomePort on the MAC you could install Parallels and install an pre-Catalina version of OSX or Windows 10 in a virtual machine. From what I gather HomePort is not going to be updated. I swapped messages with Gil of SeimperFi on The Hull Truth.
