I have stoppe using MaxSea
for exactly all these reasons.
I wanted the routing module ..A$350..!!!!
I can buy routing from predict wind
for $30 for 3 months !!
I bought Mapmedia South Pacific
Charts some years ago only to discover that Fiji
and New Caledonia
were not included..they're on my CD...just I have to pay for the unlock codes at $300 a go...
I bought C-Map
MAX charts for ALL the Pacific Islands for a little more than that and have it in my cockpit
plotter...Ok I prefer mapmedia charts cos they look like the real thing but I'm getting used to the C-Map
BIG advantage for me not using Maxsea is now with the plotter in the cockpit
i don't have to dive down to the nav station to look at the computer.
Its a much better solution.
BTW you CAN use C-Map charts with MaxSea, but you need a special decoding module that came with V12...don't know about Navnet
...but I DO know that theres'a lot of cruisers oiut ther using MaxSea V10 that they never paid for...so they're complaints don't bear argument...
