Trimble Software Update Question

I have a tractor with Autopilot and a NavII. Will be running many different gps head units in it depending on the operation. Will be using a ez guide 500, cfx 750, and an fm 1000. The 750 and the 1000 now have too new of software to utilize the nav II because it needs to be updated also. I talked to my dealer and they say if I update the nav II it won't talk to the 500. Does anybody know what version software I can run on everything to make it all work?


Any insight is appreciated.
