Dear Furunos, I'd like to update the Vector and Raster charts over what comes preinstalled for the West Coast and Baja. I have spent a considerable amount of time on the Furuno webpage and it looks to me like a dealer has to download the C-Map. Can someone walk me thru the process? I've converted from Raymarine equipment where all you had to do was buy the chart and insert it into the plotter. Seems like Furuno is a bit more complicated. Thanks for the help.
