Cool Garmin GHC 10 autopilot malfunction

Have a ghc 10 AP on my 44 Atlamtic. While cruising last week display started saying ECU overheat shut down in 60 seconds and started counting down to shutdown. Turned unit off and now when you turn it back on you get same message. Very little Garmin support in this area, Panama City. Fl. Any ideas? Call Garmin and they said send ECU to them for exchange. Still wouldn't know what caused this to happen. Thanks for any help.

GHC10 Overheat Problem

There may be a software fix;
Changes made from version 3.00 to 3.10:

  • Added GPS as a Speed Source option. This option was added to improve performance for installations that cannot support engine tachometer input.
  • Added Rudder Rate Limiter feature. This feature can be used to reduce the load on drive units experiencing frequent high current situations that can result in 'ECU High Temperature' or 'ECU Drive Circuit Overload' errors.
