I like to give credit where credit is due.
I have had a problem with my c map card which I purchased from California
and mailed to my address in Australia
. (because it was half price)
When I installed it my Northstar 12 inch chartplotter
(also purchased from California
at half price
to units sold in Australia) The cmap card didn't work.
The Cmap agent in Australia
initially would not honor the warranty because I had purchased the unit in the USA.
I emailed Cmap USA explained the problem and also mentioned that I was a member
of "cruisers forum".
I had a new chip within 24 hours and it works grest.
