If left to my own devices I think that I would have mounted the control head at the helm. But my boat came with it mounted on the bulkhead. It seemed odd to me at first, but now I wouldn't have it any other way.
I find that aside from engage/disengage time, all adjustments are made away from the helm.
- Get the boat on course.
- Engage the drive at the helm. this looks the wheel
- Walk over to the control head, and hit "Auto" to activate the AP.
After that I do all of the tweaking underway from the cockpit, away from the helm.
