Boat Lanes download to Humminbird Onix

I downloaded a zip file from boatlanes.com, will these files work with the newer Onix models? I had a little bit of trouble transferring my waypoints from my 998 to my Onix, and I was wondering if anyone has went through the boatlanes.com files with the Onix series of graphs.

Thanks.

The files in the Zip are a folder called MATRIX, a .gpx file, and a text document. In the Matrix folder there are a 000.ht, a 001.ht, and a DATA.HWR file. Is it easy as just transferring the whole folder to a blank memory card and importing the tracks into my Onix?

Thanks.
