We are frustrated with Furuno's lack of response on this issue to date.
The image on the left is a screen shot of a genuine Navionics chart running in a Raymarine Chartplotter
The image right is of the same area, in northern Phang Nga Bay Thailand, is a screen shot of the Furuno Navnet 3D chart plotter with a Mapmedia derived Navionics chart. These charts are digitized for the Navnet 3D plotter and purchased by us at 4 times the price of the original Navionics data.
There is no tide data and no useful depth information. Further zoom reveals nothing further.
(The red squares are way points we have put on)
After protracted communication with Furuno Support we have finally been advised that they will provide the unlock code free of charge for the CMap Chart Chart which covers the Navionics chart area we purchased.
MaxSea France does confirm there may currently be shortcomings of the Navionics based MM3-V69-P00
( S. China Sea ) map data.
This will hopefully resolve the problems. We will keep you posted here when we return to Taipan in late December and update the charts.
