Q2 Support

General tips, support materials, troubleshooting help and release notes for the second generation Q Displays (released 2020). See the sidebar on how to contact Q Experience support, follow us on social media or to subscribe to our newsletter on new releases and articles.


Engine data

If no engine information is shown, check the following:


The engine is connected to the Q Display over NMEA2000 (NET port on the Q Display). If no
engine data is received, the most probable cause is that the NMEA2000 network is not
functioning properly. Make sure that the Q Display is properly connected to the NMEA2000
network, and that the NMEA2000 network has a stable 12V supply and that the network is
terminated properly. For more information on how the NMEA2000 network is connected in
your boat, contact your nearest retailer.

On the Q Display you can check what NMEA2000 devices are found by going to Info >
Peripherals > NMEA Devices. If your engine is detected it should be visible in the list with
today’s date, otherwise the timestamp shows when it was last detected.

Engine Gateway

Most engines use a NMEA2000 gateway to transform the engines signals to the NMEA2000
standard. If the NMEA2000 network is working properly, but the engine gateway is defective,
no engine data will be shown. In this case contact your boat manufacturer’s nearest retailer.

The Chart is the nautical chart shown in your Q Display’s Map application.

The charts on your Q Display are stored on a physical SD card installed in the SD card slot at
the back of the Q Display. The Q Display is compatible with Navionics+ and Navionics
Platinum+ charts.

No detailed maps shown

If you only see a rough base map on your Q Display, the chart data can not be read from the
chart card. In this case the chart card is most likely corrupted. The charts are provided by
your boat manufacturer. Contact your boat manufacturer’s nearest retailer for a replacement
or buy a new chart card here.

Chart activation and update

If you get a notification that your Navionics+ chart needs to be activated or that your
Navionics+ subscription has ended, you can do so via the Navionics Boating mobile
application using Plotter Sync. For more information on how to use Plotter Sync see here.

For more information about the Navionics+ subscription see here.

Internet connection

The Q Display is equipped with an integrated 4G/LTE modem and SIM card. The SIM card’s
connectivity can be activated using the Q App, under Subscriptions.
The internet connection enables the following features:

  • Automatic software updates – always keep your Q Display up to date via Over-the-Air
  • Weather reports – Weather reports in the Q Display and automatic warnings when
    the weather is about to take a turn for the worse.
  • WLAN Hotspot – WLAN onboard, perfect for a workday at sea.
  • Google place search – find gas stations, restaurants, and other services with ease
    directly on your Q Display.
  • Subscription support – e.g., Cloud AIS and Limitation areas.
  • Mobile application connection – connection to the mobile application.
  • Q Guard surveillance – real-time surveillance of your boat, no matter where you are.

Check internet connection status

You know that the Q Display has established an internet connection when the signal strength
icon in the lower right corner changes from white to blue (or whatever color is the accent
color in your color scheme).

If you can not establish an internet connection over 4G, check the following:

Check SIM card presence

Make sure that the SIM is recognized by the Q Display by checking the SIM status
indicator in the lower right corner of the Q Display. If a SIM card is recognized, there
will be signal bars. If no SIM card is detected, a icon with a crossed out SIM card will
be shown. If the crossed out SIM card icon is shown, remove the SIM card from the
back of the Q Display, clean the SIM card carefully with a soft cloth, and reinstall the
SIM card in the SIM card slot making sure the SIM card clicks in place. Restart the Q
Display and check the SIM card status icon again. If there is no SIM card installed in
your Q Display, you can order one for free here (shipping cost will apply).

Activate SIM card

If the SIM card is present, but no internet connection is established (the signal
indicator is white), you need to activate the Q Connected subscription in the Q App.
To do this open the Q App (instructions on linking the Q App below) and navigate to
Subscriptions, choose monthly or annual, and select the Q Connected subscription.
Fill in your information and activate. A restart of the Q Display is required for the SIM
card connectivity to activate.

The Q Display’s GPS antenna is built-in (except for the 22” and 24”, which have external
antennas). In normal conditions the Q Display finds a GPS signal in about 10 seconds from
startup. If you want to use an external NMEA2000 GPS antenna, you can do so by selecting
the GPS source in the Q Display’s settings under Settings > Data sources > Position, COG &
SOG > Choose your antenna in the list.

No GPS signal/signal lost

If you do not get a GPS signal, or the GPS signal is lost while driving, check the following:

  • Make sure that the GPS source is set to internal (Settings > Data Sources >
    Position COG & SOG > Internal). NOTE: If you are using an external antenna,
    choose that in the list.
  • As the Q Display has built-in antennas, make sure that there are no large
    metal objects, or anything else that might disturb the signal, placed on top
    of the Q Display.
  • If the boat is inside a warehouse for storage, a GPS signal may not be
    established. Move the boat outside and restart the Q Display.

Software & Software updates

The Q Display’s software is constantly being developed. New software updates will be
released Over-the-Air, meaning that they automatically will be downloaded when the Q
Display is connected to the internet.

Check that software version is up to date

You can check that your software version is up to date
by checking that your software version matches with the latest release note found here. You can find your Q Display’s software version under Settings > System > System
information > Software version.

Install update

When a software update is available it will automatically be downloaded to your Q Display
(an internet connection is required, se Internet connection on this page). When the software
package is downloaded you will get a notification asking for permission to install the
software. The Q Display can still be operated normally during the installation, however, shut
down is blocked during this time. Do not disconnect the power while the installation is in

When the installation is complete, the update will take effect after the next reboot. A
notification will appear which gives you the option to restart the Q Display immediately.
After the reboot, a notification with a link to the release notes will appear. This will tell you
what new features have been added. The release notes will always be available in Info >
Release notes.

Fuel level

Fuel level can be provided to the Q Display either via an analog fuel sensor or a NMEA2000
sensor placed in the boat’s fuel tank. For a more precise fuel level reading you can also use
the Q Display’s virtual Fuel Remaining function.
The Q Display supports up to two fuel sensors, if you only have one tank in the boat, make
sure that fuel sensor 2 is set to “ – “ in Settings > Boat settings > Fuel sensor 2, see section
13.8 in the user manual.

Analog fuel sensors

If your boat has an analog fuel sensor, make sure that the correct fuel sensor type is selected
in the Q Display’s settings under Settings > Boat settings > Fuel sensor 1 or 2 > A or E. If you
are unsure about what type of fuel sensor you have in your boat, consult the boat’s manual.
However, fuel sensor type A & E are almost mirrored, meaning that choosing the wrong type
will mirror the fuel level.

NMEA2000 Fuel sensors

If your boat is equipped with a NMEA2000 fuel sensor, make sure that this is selected in
Settings > Boat settings > Fuel sensor 1 or 2 > NMEA. When the NMEA option is selected an
Instance slider will appear below the fuel sensor type selection. Leaving the Instance on “ – “
is best in most cases, however sometimes the instance needs to be selected manually. Test
the different instances and choose the one that shows the correct value.

Virtual Fuel remaining function

For a more precise fuel level readout you can use the Fuel remaining widget. This widget can
be found in the Map- or Dashboard application’s menu under Widgets > Dashboard >
Resources > Fuel remaining. This tank uses the exact consumption from the engine to
calculate the remaining fuel, accurate to 0,1L.

How to use:
– Set the boat’s fuel tank capacity in Settings > Boat settings > Fuel tank
– Fill the boat’s fuel tank with fuel, then double press the Fuel remaining
widget to reset to full capacity. When the engine starts the widget starts
counting down based on the consumption.
– If the tank is not full, you can manually adjust the value shown by pressing
the two arrows on the widget, long pressing speeds up the adjustment
