# Surveyor + NMEA Heading/Position

{% hint style="info" %}
This is just the SonarView portion of the instructions. For the detailed hardware requirements and device specific instructions, refer [here](https://app.gitbook.com/s/OPPBWdanG78xVyb6w4vq/platform-specific-setup/nmea-position-heading-source)
{% endhint %}

1. Add your Surveyor to the devices list:

{% hint style="info" %}
As a reminder, if the Surveyor is on your network, you can use the "Detect Devices" button to autopopulate the fields.

3. Add a new session with both devices:

Here's where you should be at:

With the Surveyor powered on the network and the gateway properly configured as described in the [Surveyor instructions](https://app.gitbook.com/s/OPPBWdanG78xVyb6w4vq/platform-specific-setup/nmea-position-heading-source), you should now be able to connect to this session in discovery and use the Surveyor with GPS heading and position.
