To get SI/DI/2d/Gps:

Lowrance needs:
HDS head unit
HDS GPS antenna (this may be internal I'm not sure)
HDS 2d xducer
LSS-1 structure scan module
LSS-1 structure scan xducer


Humminbird needs
SI series head unit
Gps antenna
SI series HDSI xducer (SI/DI/2d)


Be aware that the HB DI (in a SI unit) is a computer generated image from the data received from the SI crystals

The Low HDS has internal gps, (mine does), I have the LSS 1 SS black box installed under the console dash, the 2d ducer will go where the old FF TD went, and I have to install the LSS 1 TD within 12" of the 2d TD. there is room, you just have to think it out, and go from there. The HB might be an easier install, but I prefer LOW, both should do you well.
