Send a GPX to a Garmin GPSMAP 67, 66 or 64

Where GPX files go on a GPSMAP 67, 67i, 66 series and 64 series, which models mount as a drive, and how to transfer a route straight from a browser tab.

Connects as Either, depending on the modelGPX folder Garmin/GPX on every GPSMAP: /Garmin/GPX/ on the 66 and 64, Internal Storage/Garmin/GPX on the 67

Last checked against the live app on 4 September 2026.

On every Garmin GPSMAP, a route file goes to the GPX folder inside the Garmin folder. The path is Garmin/GPX.

How you reach that folder depends on which GPSMAP you own. The GPSMAP 64 series and the GPSMAP 66 series mount as a USB drive you can open, so you can copy a file across yourself. The GPSMAP 67 and 67i never mount as a drive, which means the route travels over a file transfer connection instead.

For a GPSMAP 66 or a GPSMAP 64, plug it in, connect it on INVIA's Device page in Chrome or Edge, then send. For a GPSMAP 67 or 67i, use the same Device page and press File transfer (MTP) instead, because there is no drive for INVIA to open.

Which GPSMAP do you have#

Model How it connects GPX folder
GPSMAP 67 / 67i File transfer only. No drive ever appears Internal Storage/Garmin/GPX
GPSMAP 66s / 66st / 66i / 66sr Either. Mounts as a USB drive out of the box /Garmin/GPX/
GPSMAP 64 series USB drive only /Garmin/GPX/

Read the model number off the case rather than going by when you bought it, because Garmin still sells USB drive models alongside file transfer only models.

Send a route from the browser#

  1. Plug the GPSMAP in. Use a USB data cable rather than a charge-only cable, because a charge-only cable carries power and no data. Let the GPSMAP power on.
  2. Open the Device tab in INVIA, in Chrome or Edge. Safari and Firefox show Different browser needed and send nothing, because neither one can reach a Garmin over the cable. The rest of INVIA works in Safari and Firefox. Switch to Chrome or Edge for the send.
  3. Choose how it connects. Press USB drive for a GPSMAP 66 or 64. Press File transfer (MTP) for a GPSMAP 67 or 67i. If the GPSMAP asks on its own screen to enter file transfer, accept it so the connection can finish.
  4. Let INVIA look. The status card reads Finding your device… with the hint Leave it plugged in. This can take up to a minute. Let that minute run rather than pulling the cable, because INVIA can only find a GPSMAP that stays connected.
  5. Pick the GPSMAP when INVIA asks. The status card turns into Almost there. On a GPSMAP 66 or 64, press Select my Garmin drive →, click GARMIN in the sidebar and press Select. INVIA tells you No need to open or choose a folder inside it. Just select GARMIN itself. On a file transfer connection, press Select my Garmin →, then pick the GPSMAP 67 or 67i in the browser's chooser.
  6. Choose what to send. Press From INVIA for a saved route, ride or collection, or From computer for a GPX file you already have.
  7. Send it. The SEND TO DEVICE dialog opens. Pick Internal or SD Card if both are loaded, so the file lands where you expect to find it. Set Directional arrows to Off, Forward or Reverse, then press Send.
  8. Check it landed. The dialog reads SENT, then INVIA re-reads the GPSMAP so the file appears under On Device.

On Windows, connecting a Garmin needs INVIA Bridge, a free background app you install once, because Windows claims the GPSMAP with its own driver first. On a Mac, Chrome talks to the GPSMAP directly, so nothing else is needed. More on connecting.

Direction arrows on a GPSMAP#

Set Directional arrows to Forward or Reverse at step 7 and INVIA draws the direction of travel into the line itself, so the GPSMAP shows which way to ride the track. Forward points the way you planned the route and Reverse points the other way, and Off sends the line untouched.

The arrowheads sit along the whole line, at most about a hundred of them and never closer together than about 800 meters, so a junction reads clearly without the arrows crowding the line.

Each arrowhead is a small triangle drawn off the line and back to the same point, which means a GPSMAP following an arrowed track counts a little more distance than the ride covers. Set Directional arrows to Off when the distance the GPSMAP reports has to match the route exactly.

GPSMAP 67 and 67i#

A GPSMAP 67 or 67i never mounts as a drive. Its USB menu offers file transfer and Garmin mode only, so no cable or setting will bring a drive back. INVIA offers no drive option for a GPSMAP 67 or 67i either, which means the connection you press on the Device page is File transfer (MTP) every time.

What you see:

  • No drive in Finder on a Mac.
  • No drive letter in File Explorer on Windows.
  • The GPSMAP 67 listed as a portable device in File Explorer on Windows.

What still works:

  • INVIA sends a route to a GPSMAP 67 or 67i from a browser tab over file transfer.
  • The route files live at Internal Storage/Garmin/GPX. On Windows you reach that folder through the portable device entry in File Explorer.

What to do: press File transfer (MTP) at step 3, not USB drive. Swapping cables changes nothing, because the missing drive is how a GPSMAP 67 or 67i is built rather than a fault at your end.

On a GPSMAP 67 or 67i the GPX folder sits one level deeper than on a Zumo or a Tread, because it lives inside the Garmin folder. A route sent from INVIA lands there without you choosing a folder. If a sent route does not turn up under On Device, open Internal Storage/Garmin/GPX in File Explorer on Windows and look for it there.

GPSMAP 66 series#

The GPSMAP 66s, 66st, 66i and 66sr mount as a drive with nothing to set up, so press USB drive at step 3.

A GPSMAP 66 that used to mount and stopped mounting has had its interface setting changed, which you set back on the device itself:

  1. On the GPSMAP 66, open Setup → System → Interface.
  2. Choose the USB drive option.
  3. Plug the GPSMAP 66 in again and connect it from the Device tab.

The route files already on the GPSMAP 66 are still there, because only the connection mode changed.

GPSMAP 64 series#

The GPSMAP 64 series is drive only, with no file transfer mode to choose, so press USB drive at step 3. The file goes to /Garmin/GPX/ on the GARMIN drive that appears when you plug it in.

The file copied but nothing shows on the device#

The route file is on the GPSMAP. The GPSMAP is not showing it. Three things cause that, and the table says what to do about each.

Check What to do
The file went to the memory card instead of internal storage Send it again and pick Internal in the SEND TO DEVICE dialog
The cable came out before the write finished Plug the GPSMAP in again and send it again
The file is not in the GPX folder your model reads Put it in /Garmin/GPX/ on a GPSMAP 66 or 64, or in Internal Storage/Garmin/GPX on a GPSMAP 67

A GPX file that holds only waypoints is a fourth case. The GPSMAP files those as saved places, so they are on the GPSMAP and they work. They are not a route, and no route line is drawn. What travels with a route.

Questions

Where do GPX files go on a GPSMAP 67?

In the GPX folder inside the Garmin folder on internal storage, written as Internal Storage/Garmin/GPX. The 67 and 67i connect as a portable device rather than a drive, so on Windows you reach that folder through File Explorer instead of a drive letter.

What folder do GPX files go in on a GPSMAP 64 or 66?

The GPX folder inside the Garmin folder, written as /Garmin/GPX/, on the GARMIN drive that appears when you plug the unit in. The NewFiles inbox, where a device supports it, is emptied and converted on the next start rather than being where a file lives. Advice comes from Garmin watches and cycling computers, not from a GPSMAP.

Why doesn't my GPSMAP 67 show up as a drive on my Mac?

Because it has no mass storage mode. Its USB menu offers file transfer or Garmin mode only, so nothing mounts in Finder on any Mac. It is expected behavior, not a fault in the device, the cable or the computer.

How do I switch a GPSMAP 66 back to USB drive mode?

On the device, open Setup, then System, then Interface, and set it back to the USB drive option. The 66 series ships as a USB drive, so if yours stopped mounting, that setting is the first thing to check.

Do I need BaseCamp or Garmin Express to put a GPX on a GPSMAP?

No. Garmin Express updates maps and software rather than moving GPX files. A GPSMAP 64 or 66 takes a file copied straight into /Garmin/GPX/ on its drive, and INVIA sends a route to a connected unit from a browser tab in Chrome or Edge. On Windows you install INVIA Bridge once as well, and on a Mac nothing else is needed.

Should I answer No to the file transfer prompt on my GPSMAP?

No. On a GPSMAP 67 or 67i there is no mass storage mode to fall back to, so declining the prompt leaves nothing connected at all. Accept it and let the connection finish.
