AUTO mode. The AP35 will keep the boat on the set heading until a new mode is selected or a new heading is set with either the course dial or the PORT or STBD buttons. -
Page 22: Automatic Speed Selection
The AP35 automatically selects the HI or LO parameter set. The speed at which the AP35 changes from HI to LO (or opposite) is determined by the "Transition Speed" set in the Installation Setup Menu. -
Page 23: Navigating With The Ap35
The AP35 has the capability to use steering information from an external navigator (GPS, Chart Plotter) to direct the boat to a specific waypoint location, or through a route of waypoints. In the NAV mode, the AP35 uses the heading sensor as it's source of heading for course keeping. The steering and speed information received from the external navigator alters the set course to direct the AP35 to the destination waypoint. -
Page 24: Selecting A Different Navigator
When operating the AP35 in NAV mode to automatically steer through a route of waypoints, the AP35 will steer to the first waypoint in the route after you accept the first waypoint as the location to steer to. When you arrive at the waypoint, the AP35 will display an alert screen with the proposed new course information displayed. -
Page 25: Work-Mode
WORK button following that for the TRIM display will give access to the RUDDER display. The RUDDER value can then be set by the course dial. The RUDDER value set in WORK mode will be stored in the AP35 memory and is automatically recalled when returning to WORK mode. -

Questions and answers
Need help on setting up ap35 autopilot
To set up the Simrad AP35 autopilot:
1. Mounting Components: Install the control unit and CDI35 interface. Mount the CDI35 close to the compass and secure it using fixing screws. Connect cables as shown in the wiring diagram.
2. Software Installation Settings: During installation, access the installation settings menu. Set values including language and navigation sources. These settings are necessary for proper system function.
3. Autotune: If needed, perform Autotune in open water:
- Use a safe, open area with no nearby traffic.
- Recommended speed: below 10 knots, or about half cruising speed for displacement boats.
- Avoid planing speed.
- Best results are achieved when heading East or West.
- Autotune takes 1–2 minutes and performs S-turns.
- It sets LO speed parameters; HI speed is set to 66% of LO.
4. User Setup Menu: Adjust user settings like display visibility, heading sensor selection, and navigation sources.
5. Safety: Always verify course and position regularly, switch to Standby mode, and reduce speed in time to avoid hazards.

I have a simrad ap35 autopilot .somt know why when I turn to the right it can goes up to 70 but when o turn left it only goes up to 35 .
The likely reason for the Simrad AP35 autopilot turning more to the right (up to 70) than to the left (only up to 35) could be incorrect zero adjustment or reversed deflection settings of the rudder feedback unit. If the feedback unit is mounted upside down and not properly configured, it can cause incorrect pointer deflection and unequal steering response. Performing a reversed deflection correction or redoing the zero adjust may resolve the issue.
