I've tried it both ways: waypt ack off and on, and with APB, and with ECapb and ECrmb as suggested. They all seem to behave the same way. It does not follow the protocol shown in the user guide... says route
ends instead of next waypt?
I can of course reset GPS auto mode and it will then steer to the next waypoint and alarm when it gets there. For routes where the wp are far apart, this isn't a problem, but one of the few times I have used this feature (with my old Northstar GPS) was running a tricky entrance with several quick turns, in the pitch
black and with a cyclone approaching (Vanuatu). Worked well then, allowing both Ann and I to concentrate on peering into the black and hoping to see the reef before we hit it... if the A/P failed! A scary night... and having to go through the reset at each wp wouln't play well, I fear.
Thanks for your thoughts on this, Jon.
