Idlewild autopilot problems

We have a Comnav 1001 autopilot that we have generally been frustrated with.
I think the Comnav is good, but trouble with the instalation that we don't
understand.  The installer clearly didn't appreciate the system and my
experience was nil so I didn't know exactly what to expect or what was wrong
or how to explain it.  Consequently we kept losing feed from GPS to computer
etc.  The only thing that would work was off the fluxgate compass.  The
compass feed stopped when we got far north and we had nothing.  Phone calls
gave us no help.  Hand steering in the Arctic at night or in fog with no
compass in storms was a nightmare.  After 12000 nm of travel a crewman
suggested unhooking one GPS feed from the terminal and then finally
we were able to
use our Garmin GPSMap172c with a route and follow that.  It would have been
great to have that in the Arctic.

It would be more practical to use the laptop, but we are worried that would
entail more problems and the 172 is working OK although whenever we start it
on a route it will go about 350 feet to port then about 90 feet to starboard
before settling on the route.  With this habit we need to be well out to sea
before engaging it.

We had been told that each GPS should feed 4 or 5 units and we tried it but
would soon lose our Nav feed so we unhooked our radar, VHF, SSB and now just
run one GPS to the computer and the other to the autopilot.

Regards,
Ben

Could Ben please comment on the performance of his Navman autopilot?

Which model does he have?

Thank you,
