[C320-list] Raymarine RL70CRC and C-Map NT+ Chip Failure

[Amirault Family]

Greetings:

Now that the list has overcome my incompetence regarding regarding gas 
stove usage, I am moving on to the next issue with learning the quirks 
of Bear's equipment. She came from Michigan with a chartplotter/radar 
complete with C-Map chips for her home area.  I removed these and 
installed a new C-Map NT+ chip for her new waters purchased from the 
local chandlery; although it required a special order. The GPS works and 
can find me on the plotter internal world map.

Following the instructions (read repeatedly) I zoomed in on the map, 
which should cause the plotter to check for  pertinent chart data and if 
finding same, leave the world map. The plotter fails to do so, allowing 
me to only zoom in to 150 nm before the chart loses display.

Can anyone suggest the thing I am not doing which is preventing the 
plotter from recognizing that there is a local chart chip in the 
plotter? Note that the chip design allows for only one orientation of 
the chip for insertion. Failing this I will start with the Raymarine 
help number and if no relief is found there continue on to C-Map.
