I am looking for the Cetrek 618 installation manual for an old unit that I am restoring back into action.

I have a Cetrek 727 head unit and a 305 Rudder display.

I also have a Cetrek compass interfacee that I cannot find any details for this as well as a Cetrek compass sensor as well as a Compass heading gauge model 930-460 and a Cetrek Multi.

I also have the rudder reference unit for this package. It was taken from a vessel in working condition and I am retrofitting it to another vessel but no one have any documentation for it.

Any help with copies of manuals would be most appreciated.

Regards Ian
