EV-200 turns to port

landingzone,

Early versions of Evolution autopilot software were quite sensitive to having very good speed through water data. The software within your Evolution autopilot ACU, EV-1, and p70R are very old and in need of updating. The software within these products is designed to be updated via any of the MFD's listed on the Evolution ACU, EV-1 Sensor Core, and p70R product software update web pages respectively. Alternatively, the software may be updated by a Certified Raymarine Installer or Raymarine’s Product Repair Center.
