I have just installed Open CPN
on Windows 8. I can not get it to recognize my GPS
(BU-353). I followed all of the instructions, still no luck. I see that there is a work around by installing "Xport" but it says that the product is no longer available.
I don't believe that the problem is with the GPS
as I am able to get it to work with Polar View.
I had a similar problem on Windows 7 except that it would sometimes work and sometimes not. On a few occasions, it crashed the computer.
I love this product and desperately want to get it up and running.
