EV-1 Linearization Problems

[Steve - Raymarine - Moderator]

The issue will be the EV-1 Heading sensor, for the issues you are explaining and that is the only unit that needs to be sent in. Unfortunately it does sound like an issue, with the troubleshooting you have tried so far. The unit can be sent to the below address to be evaluated by a service technician for repair or replacement. You can include a note to call with shipping information back to you, so when it is ready the technician will call and you can tell him where to send it back.
