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

[Amirault Family]

Dave:

Was at the boat this afternoon to thread coloured line onto the anchor 
rode every 5 feet; a pleasant enough activity to do on a sunny windless 
Sunday afternoon sitting in the cockpit under the awning watching the 
boats go to and from the service dock while talking to the other owners 
walking to and from their slips.

What I found from the chart plotter was that on startup it generates the 
Raytheon logo rather than the Raymarine, which Raymarine claims means I 
cannot use C-MAP NT+ chips. On the GPS getting a fix, the plotter did 
not recognize my local NT+ chip in either card slot. It did not 
recognize the NT+ chip I found in the plotter when the boat arrived in 
Ottawa. It DID recognize the NT chip which was also in the plotter on 
arrival. Thus I'm ready for Lake Michigan in the event that I ever 
travel there.

The solution is to attempt to get a local NT chip if one is available, 
or to get a refund for the NT+ chip. I will not spend the $800 US to 
upgrade the hardware in the plotter to NT+ compatible. I have sailed the 
same confined river waters for 5 years and know them. I  have been using 
a paper chart and will continue to do so until I move to bigger water in 
another 5 years. At that time I will upgrade to the then latest consumer 
plotter hardware/software combination.

I thank everyone for their assistance and suggestions.
