I have the old style EZ Guide and I am using it to get GPS to my PF3000.  My PF3000 is showing that I am getting signal, at least it has the -G at the top of the screen.  Whenever I work the hand pad to go to guidance with the light bar, I get various codes on the light bar screen, AOW SRCH, POR SRCH, G-3D 09, G/3D 09, and No D-3D.  I would like to use the light bar while I am using it for my yield monitor as a row finder.  What are these codes meaning?  Do I need a soft ware update?  I had the last one done, probably a year and a half ago.  Thanks for your time!  Remember this is just an EZ Guide, not the newer +.  Howard
