And thanks for the information gentlemen. I installed 1.55 on the 132 this morning. The install went fine with no problems at all. But, the unit reset to the factory defaults after the update, and then started looking for an Omnistar subscription. After I went through and reset every thing that I could remember (a mind is a terrible thing to loose) the unit locked right on to 135. I think I got all the port settings reset and the 5Hz rate running again. The guidance unit is not in that tractor right now. I am sure I will have to tweak some settings when it goes back in.

But, there is life in the old girl yet.
