Well... for the last 6-7 years I have kept my waypoints and routes in a FileMaker database I developed, and then transfer those I need on a particular voyage into my GPS and now iNavX. The transfer to or from the GPS was done by MacGPS Pro.
Tonight I finally purchased MacENC and have now transferred all my waypoints and routes into that. The waypoint groups are really great for organising the waypoints by region. I intend to abandon my old system.
What I really want (I think) is a way to synchronise these waypoints and routes between MacENC and iNavX, so that they all (or selected groups) are transferred. I say synchronise, because when I add, amend or delete a waypoint in MacENC, that needs to be reflected in iNavX, and, conversely, if a waypoint or route is added, amended or deleted within iNavX it needs to find its way into MacGPS.
I am aware synchronising is a complex task, especially as conflicts need resolving, and you cannot rely on a waypoint or route name to identify it because the name may be changed, and that needs synchronising. But the techniques are well known now.
This would be way beyond NMEA data streams, so some other protocol would be needed, such as is used to synchronise various Mac and iPhone databases. If it means suspending NMEA data transfer while synchronising, that's fine - it can be an off-line task.
I realise this may be a big task, but you did ask what was wanted.
PS I am really enjoying exploring MacENC - just need some charts and connections now.
