Garmin not connecting, or the GPX not showing up

Most Garmins sold today never appear on your computer.

They have no USB drive mode and they connect over file transfer the way a phone does, so File Explorer shows no drive letter and Finder shows no volume. The cable, the port and the Garmin are all working.

Connect the Garmin on INVIA's Device page in Chrome or Edge, then send the route.

The route I sent is not in INVIA's device list#

Fit a memory card in a Zumo XT2, Zumo XT3 or Tread. Send your routes to the card.

A Zumo XT2, Zumo XT3 or Tread copies a route from internal storage into its own database on the first restart after the send, and then deletes the file it read.

After that restart:

• Your route is still on the Garmin. It is in the Garmin's own list and you can ride it.
• Your route is not in the device list. Your waypoints are still listed. Your tracks are not, because a Zumo XT2, Zumo XT3 or Tread never writes a track back to a file.
• The route file is gone from internal storage, which means you can no longer copy it back off or back it up.

INVIA lists the files it finds on the Garmin. A Zumo XT2, Zumo XT3 or Tread keeps its waypoints in a file of its own and never deletes that file, which is why your waypoints keep appearing after the restart. The Garmin's own export writes waypoints and never writes tracks, so nothing puts the route back in the list.

Send to a memory card instead, because the file survives the restart and the route still imports, which means you keep the ride on the Garmin and the file in INVIA's list. In the send dialog, choose SD Card. Where each Garmin keeps your tracks, folder by folder.

Nothing appears on the computer when I plug the Garmin in#

Find your model in the table, because the lineup splits into Garmins that mount as a drive and Garmins that never do.

The Garmins in the first two rows connect over file transfer only, so press File transfer (MTP) on the Device page. Pressing USB drive finds nothing on those Garmins, and no port, hub or cable swap makes a drive appear, because there is no drive to find.

The Garmins in the last two rows mount as a drive, so press USB drive on the Device page.

If your Garmin is in the last two rows and no drive appeared, the cable or the port is the likely cause.

1. Swap the cable for one that carries data, because a cable supplied with a phone charger is often charge-only, and a charge-only cable charges the Garmin without making a drive appear.
2. Try a different USB port before you decide the Garmin is at fault.

A drive appeared, but I expected file transfer#

Press USB drive, not File transfer (MTP). Yours is a drive model, which takes fewer steps than the file transfer path.

INVIA tells you when it finds a drive Garmin while you are on the file transfer path, and the hint reads {device name} shows up as a USB drive. Use USB drive.

Selecting the drive is the one step that needs you, because a web page reaches a drive only after you have picked that drive yourself.

1. Press Select my Garmin drive →.
2. Click GARMIN in the sidebar of the window that opens.
3. Click Select.

Select the drive itself rather than a folder inside it, because the Garmin tells INVIA where its own GPX folder is, so the folder is never something you have to find.

Safari and Firefox cannot reach the Garmin#

Use Chrome or Edge, because they are the only browsers that let a web page talk to a USB device or open a drive.

On a Mac, Safari and Firefox show Different browser needed. The Garmin and the cable are both fine, so open INVIA in Chrome or Edge and connect again.

It keeps saying it is looking for the device#

Leave the cable in and wait. A Garmin takes time to offer file transfer, so a card that says it is still looking is counting through that wait rather than reporting a failure.

The card reads Finding your device… with the hint Leave it plugged in. This can take up to a minute. INVIA's device help puts the wait at up to about 40 seconds. INVIA keeps trying on its own for that whole wait, so there is nothing for you to press.

A Zumo XT enters file transfer roughly 20 seconds after the cable goes in, even when powered off. Each attempt runs its own clock, so unplugging at 15 seconds and trying again starts the whole wait over.

On a Mac one other thing can hold the Garmin, because the system camera service or another application such as Garmin Express can take a file transfer Garmin before INVIA reaches it. INVIA tells you when that happens.

1. Quit that application, or unplug the cable and plug it back in.
2. Connect again on the Device page.

The Garmin asks on screen about file transfer#

Tap Yes on the Garmin screen, because until you tap Yes the computer does not see the Garmin at all.

That silence looks the same as a dead cable, which is why so many riders order a replacement cable when the cable was never the problem.

To stop being asked, set USB Mode to MTP on the Garmin at Setup, System, USB Mode, and the Garmin then enters file transfer on its own.

Windows wants me to install a bridge application#

Install it. On Windows, INVIA reaches every Garmin through INVIA Bridge, a small free background application. That covers drive models as well as file transfer models, because Windows does not let a browser talk to a Garmin on its own.

Until INVIA Bridge is running, the Device page shows Connect your Garmin on Windows with a Download INVIA Bridge button. The install is one time.

1. Press Download INVIA Bridge and run the installer.
2. If Windows shows Windows protected your PC on first launch, click More info → Run anyway.
3. If INVIA Bridge is already installed, use Bridge already running? Click here to connect.

A drive you granted access to in an earlier session skips all of this, because the browser remembers that permission and reconnects with no prompt.

A Mac needs nothing extra either way, since INVIA sends from a browser tab on a Mac and INVIA Bridge carries that same connection on Windows.

The browser asked me to pick a device#

That chooser is a privacy step built into the browser rather than an error, and it comes up whenever INVIA's silent search finds nothing, so it is not only a first connect. Swapping Garmins or a lapsed drive permission brings it back.

Once you have picked a file transfer Garmin, plugging it back in normally reconnects with no dialog at all, because the browser keeps that choice.

The file sent but I cannot find it on the Garmin#

Work through this in order.

1. Check the folder for your model in the table above. Garmin/NewFiles is real on some handhelds, but it is an import inbox rather than the folder a file lives in, because the Garmin takes what you leave there on the next restart. The GPX folder is where a file stays and is read from.
2. Check internal storage against the memory card. INVIA sends to internal storage unless you choose SD Card, so look on the memory card for a route you cannot find.
3. Look in the right menu. INVIA delivers a route as a track, so it lands under Track Manager, Trip Planner or Tracks depending on the model, rather than in a list of destinations.
4. Restart the Garmin and check again, especially if the transfer was still running when you looked.
5. Confirm it is there. After a send, INVIA re-reads the Garmin and lists the file under On Device. Press ↺ Refresh to read the Garmin again, and check that list before you unplug.

My Montana 700 shows up as a drive#

That is how it ships, because the Montana 700, 700i and 750i mount as a USB drive out of the box. Press USB drive.

File transfer is an opt-in setting at Setup → System → Interface, so use USB drive unless you switched that setting yourself. Check that setting first if a Montana 700 that used to appear stops appearing.

The GPSMAP 66 series works the same way. Full detail on the Montana family.

Windows will not recognize my Montana 760i#

The Montana 760i has a known Windows driver quirk, so Windows may not react at all until you choose the file transfer driver by hand in Device Manager.

If the Montana 760i charges and the computer does not react:

1. Open Device Manager and choose the file transfer driver for the Montana 760i by hand.
2. Start INVIA Bridge.
3. Connect again on the Device page.

The memory card is not a separate drive#

On a file transfer Garmin, a fitted memory card is a second storage inside the same connection, so it is not a volume you can mount and there is no card-based workaround.

INVIA lists both storages, and the send dialog offers Internal or SD Card when both are loaded.

On a drive Garmin the memory card mounts as its own volume, so press Add memory card to load it.

Does importing delete my tracks#

No. Importing copies. INVIA offers to clear tracks from the Garmin only after it verifies that the import arrived intact, and clearing is a separate step that you confirm.

If verification fails, INVIA does not clear anything. The tracks stay on the Garmin.

Advice you will find that no longer works#

• Switch it to mass storage mode. No such mode exists on the Zumo XT and XT2, the Tread family or the Montana 710, 710i and 760i. It does not exist on the GPSMAP 67 and 67i or the eTrex SE and Solar either. Garmin has confirmed it is not returning, so press File transfer (MTP) instead.
• Install Android File Transfer. INVIA does not need it, because on a Mac Chrome or Edge reaches a file transfer Garmin directly.
• Open it in BaseCamp. BaseCamp works on drive-mounting models and cannot see a Garmin that never mounts as a drive, so send from INVIA instead.
• Drag it into Garmin Express. Garmin Express updates maps and software and does not import GPX files, so send from INVIA instead.
• Try another port, do not use a hub. That is fine on a drive model. It changes nothing on a Garmin that never mounts as a drive, so press File transfer (MTP) instead.

Windows does have one manual path, because a file transfer Garmin appears under Portable Devices in File Explorer and you can drag a GPX into its GPX folder yourself.

A Mac has no equivalent, because macOS has no built-in support for that connection, so on a Mac send the route from INVIA in Chrome or Edge instead.

No computer at hand#

The browser path needs a computer, because INVIA does not transfer over Bluetooth or wifi.

1. Export the route as a standard GPX file.
2. Share it to the Garmin Tread app for a Tread, or the Garmin Explore app for a handheld.

For the connection itself, see connecting a Garmin or the full model table.
