Raymarine navigation chip
TI have a Raymarine A series unit that came with a used boat. There is a microSD navigation chip in it, but it is pretty much useless as it is not very specific to this Lake.
I am looking for advice - buy the Navionics chip or one from Bizer (assuming they have one that fits). The boat will only be used on Winnipesaukee.
Thanks for any guidance.
