This reply may cause more frustration than anything else. I do have a manual for the Cetrek Propilot 700 which uses the 930670
compass controller and the 930683
Power Interface. I don't know if that information would be of any help.
The other drawback is the manual I have is in hard copy and I'm in
New Zealand. However, if you had a specific question, I'd be happy to look it up.
