I bought an iPad in 2012 and Navionics charts as back up, to take us across the Pacific, Indian and Atlantic Oceans. This was a one-off purchase. I am now planning on entering the eastern Mediterranean and it appears that I can only take out an annual subscription for £49.99. Does any one know if this is the only possibility are are there other options? I know it's not a lot of money and the C-Map SD card for the chartplotter for the same area costs £199.20 i.e. same price over 4 years.
Incidentally I have started a new thread because the existing Navionics thread is about accuracy.
