*RESOLVED!!!*
Gentleman on BBC Forums helped me.
Create a folder on computer named "MATRIX". Copy .hpw file into MATRIX folder. Copy "MATRIX" folder onto SD card. Insert card into Helix and viola! I've spent close to 3-4hrs this AM trying to figure out how to do this without Humminbird PC and he replied within minutes with a simple 30 second procedure. The power of the www. is incredible.
