You might want to try the factory reset. They told me in an email
No power to the TP32 press and hold Port. Tack, Starboard and Nav.
Power up the TP32 while holding the buttons in. The LED's on the unit will blink Indication the reset.
Thank you for choosing Navico
This spring I had two TP-32s that were misbehaving. Navico sent me these instructions for restoring the factory default settings. That and a compass
calibration using the instructions in the owners manual fixed them both. Be careful that you do not change the tillerpilot from stbd mount to port mount. The instructions for fixing that problem are also in the owners manual.
