 ====== Garmin MFD integration ======
-Preliminary manual
-===== Introduction =====
+===== 1. Introduction =====
+This document explains how to connect to Garmin MFDs using an Ethernet connection.
 The integration technology used is called [[https://www.garmin.com/en-US/onehelm|Garmin OneHelm]].
-===== Compatibility =====
+Make sure to also study the [[https://www.victronenergy.com/live/ccgx:start#marine_mfd_integration_by_app|Marine MFD Integration by App chapter in the manual]].
-OneHelm is currently available for the GPSMAP® 8400/8600 MFD series.
+Note that there is an alternative method to connect, which is NMEA2000. See the [[https://www.victronenergy.com/live/ccgx:start#marine_mfd_integration_by_nmea_2000|NMEA2000 chapter in the main manual]].
+===== 2. Compatibility =====
+OneHelm is currently available for the following models:
+  * GPSMAP® 8400/8600 MFD series
+  * GPSMAP® 722/922/1222 Plus MFD series
 Also, Active Captain is supported. This screenshot shows ActiveCaptain, with the Victron App:

-===== Wiring =====
+===== 3. Wiring =====
 The Garmin needs to be connected to the [[https://www.victronenergy.com/live/venus-os:start|GX device ]] using Ethernet. Its not possible to connect over WiFi. For the ethernet connection, a Garmin adapter is required:

-===== Configuration =====
-==== GX device settings ====
+===== 4. Configuration =====
+==== 4.1. GX device settings ====
-  - Ordered List Item
+  - Go to //Settings -> Services//, and there enable both //MQTT on LAN (SSL)// and //MQTT on LAN (Plaintext)//.{{:venus-os:venus-html5-mqtt.png?400|}}
-  - Go to Settings -> Services, and there enable MQTT.
+  - Go to //Settings -> System Setup -> Scroll to the bottom -> Marine MFD App configuration//. And there set up what batteries you want to see on the MFD, and by what name. Make sure to check out [[https://www.dropbox.com/s/nlvqttx320zyaba/Battery%20Measurements.mov?dl=0|this video, which shows how to configure the batteries to be visible on the MFD]]. {{:venus-os:venus-html5-batteries1.png?400|}}{{:venus-os:venus-html5-batteries2.png?400|}}
-  - Go to Settings -> System Setup -> Scroll to the bottom -> Battery measurements. And there set up what batteries you want to see on the MFD, and by what name. Make sure to check out [[https://www.dropbox.com/s/nlvqttx320zyaba/Battery%20Measurements.mov?dl=0|this video, which shows how to configure the batteries to be visible on the MFD]]
   - For boats; and other applications with DC loads such as lighting and a Battery Monitor installed, make sure to enable the "Has DC system setting". For more information about it; see the [[https://www.victronenergy.com/live/ccgx:start|GX Manual]].
-==== Networking ====
+==== 4.2. Networking ====
 No special networking settings are necessary. Not on the Garmin; and not on the Victron GX Device.
 The Garmin MFDs run a DHCP server; and the [[https://www.victronenergy.com/live/ccgx:start|GX device]] are by default configured to use DHCP. After plugging in the cable, the Victron icon will show up after 10 to 30 seconds.
-It is possible to connect the Garmin MFD to the Ethernet port of the GX device, and connect to the internet and VRM on the GX device by using [[https://www.victronenergy.com/live/ccgx:start#internet_connectivity| one of the other non-ethernet port internet connectivity options (eg Wifi interface, or GX GSM).]]
+To connect the GX Device to the internet and the [[https://vrm.victronenergy.com|VRM Portal]], while its Ethernet port is already in use to connect to the Garmin, use WiFi. [[https://www.victronenergy.com/live/ccgx:start#internet_connectivity|more information]].
-===== Usage =====
+:!: Connecting a Garmin MFD to a network router over Ethernet leads to IP address conflicts, due to the integrated DHCP server.
+:!: It is not possible to use a [[https://www.victronenergy.com/accessories/gx-gsm|GX GSM]], due to the integrated DHCP server of the Garmin MFD.

+===== 7. NMEA 2000 =====
+The MFD can also be connected to the GX device using NMEA 2000, see [[https://www.victronenergy.com/live/ccgx:start#marine_mfd_integration_by_nmea_2000|NMEA2000 chapter in the main manual]].
+The MFD can be configured easily to display the data from the GX device. There is no need to change any instance.\\
+To setup NMEA 2000 on the MFD, go to //Settings > Communications > NMEA 2000 Setup > Device List//. Here you can view information about the connected products and change their names. Note that the names are stored on the MFD and not on the NMEA 2000 device.
+The following Victron related PGNs are supported:
+  * 127505 - Fluid level (tanks)
+  * 127506 - DC Detailed Status; State-of-charge, Time-to-go
+  * 127508 - Battery Status; Voltage, current
+The supported PGNs may vary per model. Please consult the manual of the MFD for a list of supported PGNs.
-TBD add screenshots and so forth.
