How to Update Garmin LiveScope

How to update Garmin LiveScope: you update the Garmin chartplotter it is connected to, with the LiveScope powered on. Garmin’s update bundle notes say that when the update completes, the Garmin Marine Network devices on the boat have the latest software too. Garmin’s chartplotter manuals give three ways to do it: the ActiveCaptain app on a phone (for chartplotters with Wi-Fi), the Garmin Express desktop app writing the update to a memory card, or Garmin’s software update bundle copied to a microSD card by hand. This guide walks through each route, how to check the version you have, and what to look at when an update does not finish. The steps come from Garmin’s LiveScope installation instructions, its GPSMAP and ECHOMAP UHD2 owner’s manuals, and its marine software update page; menu names on other chartplotter lines can differ, so keep your own manual open.

When You Need to Update LiveScope

The first update is part of the install. Every LiveScope installation guide we checked says the same thing in its opening section: “You must update the Garmin chartplotter software when you install this device.” That line appears in the instructions for the original Panoptix LiveScope (LVS32), LiveScope Plus (LVS34), LiveScope XR (LVS62), and LiveScope 2 (LVS42 and LVS44) transducers, and each one sends you to the chartplotter’s owner’s manual for the procedure. None of them describes a separate updater for the sonar itself.

Three other moments call for it:

• Adding a newer transducer to an older black box. Garmin’s LiveScope Plus announcement says that with a free software update, the LVS34 transducer can be added to an existing LiveScope system black box.
• Adding any new device or accessory. The ECHOMAP UHD2 manual’s software update page says you may need to update the software when you install a new device or add an accessory.
• When Garmin lists a newer version. The manuals say to compare your installed version with the one on Garmin’s site and update if yours is older. Garmin also notes that updates bring changes and improvements to privacy, security, and features.

Check the Software Version First

On GPSMAP and ECHOMAP UHD2 chartplotters, open the menu and select System > System Information > Software Information to see the installed software version. Then go to Garmin’s marine device software updates page, find the bundle for your chartplotter family, and select See All Devices in this Bundle. That list shows the latest software version for each product the bundle covers. The GPSMAP and echoMAP bundle lists we opened both include the Panoptix LiveScope GLS10 sonar module, the black box used with the LVS32, LVS34, and LVS62 transducers, under Sonar Modules.

Before updating, it also helps to confirm the chartplotter sees the LiveScope at all. The GPSMAP owner’s manual lists connected devices under Communications: select a network, then Device List. If the sonar does not appear there, sort out the connection before updating.

How to Update Garmin LiveScope With an SD Card

The card goes into a slot on your primary chartplotter; Garmin’s bundle notes say that if you have no primary device with a card slot, see your dealer for assistance. You can load the card two ways.

Option 1: Load the card with Garmin Express

Garmin’s manuals recommend Express for large downloads, since it is faster and avoids possible mobile data charges. Use a blank card: the process erases and reformats it.

1. Insert the memory card into your computer’s card slot.
2. Install Garmin Express on a Windows or Mac computer and open it.
3. Select your vessel and device, then Software Updates > Continue, and agree to the terms.
4. Select the drive for the card, review the reformat warning, and select Continue.
5. Wait while the update copies. Garmin says this can take from a few minutes up to a few hours.
6. Close Express and eject the card.

Option 2: Download the update bundle yourself

The marine software page also offers each bundle as a free download, or on a preloaded card you can buy. The notes for the GPSMAP series bundle say to unzip the download and drag the Garmin folder onto a microSD card, where it should be the only item. When we checked, those notes called for a FAT32 card between 16 GB and 32 GB; the echoMAP series bundle allowed 8 GB to 32 GB. Both say to back up your user data first and to avoid using your existing ActiveCaptain card or a mapping card, because the data on it could be lost.

Install the update from the card

1. Turn on the chartplotter, and make sure the LiveScope and every other attached network device are powered on as well. Garmin’s bundle notes call this out.
2. Wait for the home screen. Garmin says the chartplotter must be fully booted before you insert the card, or the update instructions will not appear.
3. Insert the card into the slot on your primary chartplotter, then select Install Now > Update Software > Yes.
4. Wait. The manuals say several minutes; the bundle notes add that 20 minutes or more is not uncommon, especially on larger networks.
5. When prompted, leave the card in place and restart the chartplotter. Remove the card only after it has fully restarted; Garmin says pulling it early leaves the update incomplete.

According to the bundle notes, once the update completes, all Garmin Marine Network devices and NMEA 2000 sensors have the latest software. You can watch the sonar while it runs: on the GLS 10 sonar module and on the LiveScope 2 transducer, Garmin’s installation instructions say an orange blinking status LED means a software update is in progress.

How to Update LiveScope With the ActiveCaptain App

If your chartplotter has Wi-Fi, the GPSMAP and ECHOMAP UHD2 manuals let you update through the ActiveCaptain app. Setup comes first, per the GPSMAP manual: turn on the chartplotter’s Wi-Fi network from its ActiveCaptain page, insert a memory card and select Set ActiveCaptain Card, and connect the app. Garmin says the card has to be inserted each time you use the ActiveCaptain feature. Then:

1. With the phone connected to the internet and an update available, select Software Updates > Download in the app. The update downloads to the phone.
2. Reconnect the app to the chartplotter. The update transfers, and the chartplotter prompts you to install it.
3. Select OK to install now, or Cancel to wait and later select ActiveCaptain > Software Updates > Install Now.

Garmin warns that updates can be large files subject to your mobile data limits or charges, and that installation can take several minutes. The GPSMAP manual says updates started from the app update all connected devices when the ActiveCaptain card sits in a Garmin BlueNet chartplotter, so keep the LiveScope powered on through the install.

If the Update Does Not Finish or LiveScope Is Not Updated

• No update prompt. Garmin says the chartplotter must be fully booted before the card goes in. Remove it, wait for the home screen, and insert it again.
• Card pulled too early. If the card came out before the full restart, Garmin says the update is not complete, so run it again.
• The sonar was off. If the LiveScope was not powered during the update, it may not have received it. Power everything on and repeat the card update.
• Red blinking LED. On the GLS 10, this means the module is on but not connected to a chartplotter, or is waiting to connect; the LiveScope 2 transducer uses the same color for awaiting a connection. If it persists while connected, Garmin says to check the wiring connections. Follow the installation instructions for that, or have a qualified marine installer look at it.
• A second chartplotter on NMEA 2000 only. The bundle notes say chartplotters connected by NMEA 2000 and not the Garmin Marine Network have to be updated one at a time with the same card, after the network update finishes.
• Mixed Garmin BlueNet and older networks. The GPSMAP manual says that when an older Garmin Marine Network chartplotter is joined to a BlueNet network, the ActiveCaptain card belongs in a BlueNet chartplotter. Put it in the older unit, and updates started from the app reach only the older network’s devices.

If none of these fits and the update still fails, skip repeated retries and contact Garmin’s product support or the dealer that installed the system, with your chartplotter model and its Software Information screen at hand.

Once LiveScope is current, our forward-facing sonar section covers setup and use. How we research these guides is on our How We Review page.

Frequently Asked Questions

How do I update my Garmin LiveScope?

Update the Garmin chartplotter it connects to, with the LiveScope powered on, using a memory card loaded by Garmin Express, the downloaded update bundle, or the ActiveCaptain app. The LiveScope installation instructions point to the chartplotter’s manual for the procedure rather than a separate sonar updater.

Do I need a software update to add an LVS34 to my LiveScope?

Yes. Garmin’s LiveScope Plus announcement says a free software update lets the LVS34 transducer be added to an existing LiveScope black box, and the LVS34 installation instructions say you must update the chartplotter software when you install it.

What is the latest Garmin LiveScope update?

Version numbers change with each release, so check the source: on Garmin’s marine software page, open See All Devices in this Bundle for your chartplotter family and, for a GLS 10 based system, find the Panoptix LiveScope GLS10 entry, then compare with what your chartplotter’s Software Information screen shows.

How long does a LiveScope update take?

Plan for a while. Loading the card in Garmin Express can take from a few minutes up to a few hours, and Garmin’s bundle notes say an install of 20 minutes or more is not uncommon, especially on larger networks. Leave the card in until the chartplotter has fully restarted.
