Mine is about troubleshooting my voltage drop, and fitting a new AP. I picked up a Raymarine Evolution wheel pilot during the Defender sale, thinking it would be a backup to my below deck AP. But after speaking with Ray tech support I'm now planning to make it my primary. They've come a long way in control sophistication, and this new-gen control technology is far superior in accuracy and response, even to my gyro-augmented course computer. It would be very easy to install if I had all new stuff, but I need to make sure I have all the right wiring and converters to integrate my older instruments and NMEA stuff.
