I have a 2 year old sailing catamaran that had a single FAP711 autopilot controller. I have just connected a second FAP711 with wiring and jumper connection as per instalation manual to switch mode. The new unit has booted in simulation mode and I am unable to open the instalation menu. The original unit still works as previous and the instalation menu opens as per the manual. Both units power each other up and down - so it looks like the wiring is good. Thanks for any assistance.
