Mass Storage (works on one computer but not the other)

Has Garmin Express been installed on the laptop? When installing Garmin Express, have the GPS plugged in to the computer or laptop. Garmin Express will detect the GPS and install Garmin USB drivers. The laptop will see the GPS after that.

Is the laptop running Win10? Folks sometimes have issues with mtp mode so try switching your nuvi to mass storage mode. That's if your nuvi I is normally in mtp mode, sorry cant recall if that is used on that model.

Yes, the 3597 uses MTP mode by default.

OK, I've reinstalled the Garmin driver. No change.
When connected to my Dell laptop the 3597 will not switch to MTP mode. My 3590 and Montana will switch. With the Montana I'm even using the same cable.
When the 3597 is connected to my Acer laptop or desktop computer, it immediately switches into MTP mode.
All three computers are operating with Win 10.
If I connect the 3597 to the Dell the 3597 immediately is turned on, but not in MTP mode.
Thanks all for the suggestions

Are you by chance plugging into a USB 3 port? I've found some systems going through a USB 3 port persnikety..

I would try what sussamb suggested. Switch your 3597 from MTP mode to mass storage mode and see if it connects to the Dell.

The 3597 has been set to "Mass Storage" since I first received it and set it up.
Incidentally, I just changed it to "Auto Detect MTP" to see what would happen and still nothing on the Dell.

I read somewhere that Microsoft screwed up an automatic update for the MTP driver back in March and then rescinded it, so just to see if that was the cause I reinstalled a backup January image of my C: drive. Results were the same.

The Dell has 2 USB2 and a USB3 port. I have tried all 3 as well as a multitude of cables, including those branded with the Garmin name.

Thanks to all for the suggestions

Try deleting the 3597 in Garmin Express and re-detecting it:

Make sure the GPS battery is charged.

Unplug the GPS from the laptop.

Open Garmin Express. If there is an icon for the 3597, right-click it and choose "Remove From Express."

Restart the laptop and restart the GPS. (not just sleep) Hold the power button for 4 seconds for a popup and touch "Off."

Open Garmin Express. Plug the GPS into a USB 2 port using the USB cable that came with it. Watch for a couple of minutes whether the GPS is detected - probably not.

In Garmin Express click the + icon to "Add a Device." Give it several minutes to detect the GPS.

If the above does not work try these links:

Many thanks to all who made suggestions. Even Garmin was short on providing a resolution.

I started connecting the 3597 with all of my cables. Finally one which came with an external drive case made the connection. This particular cable had 2 USB type A plugs on one end and a USB mini on the other. I connected both USB A plugs to the computer and the mini to the GPS. Voila; it worked!
Now, for some strange reason all of the cables that previously did not work are OK.

I had found on another forum where many individuals reported connection issues, particularly between a 3597 and a Dell computer. One suggestion that worked for some was to use a USB hub between the GPSr and the computer. I did not have one, so just started trying various cables.

Thanks for getting back to us. We are happy it was resolved!

I have a couple external shirtpocket drives that won't work on wife's laptop until I plug in 2 USB connectors on computer end...
Our Laptop exhibiting this is HP, our Dell's work fine with single ended USB Cable....

Has something to do with the amount of power the USB Port can supply I believe, as the 2nd USB Connector on Computer end only provides Power...

Your experience with the double USB cable as well as JanJ's experience seem to show that the GPS's battery was depleted and the double connector supplied more power.

The reason all your USB cables work now is that the GPS battery may be fully charged.

Whenever loading POIs or updating the map or software, charge the GPS battery beforehand. Ordinary USB ports supply 1/2 amp, a slow charging rate, while the Garmin wall charger supplies 1 amp.

That is a very unique issue. Suprised it works on one and not the other?

The GPS had a full charge and the laptop was connected to it's charger.

As noted earlier, the GPS would not connect to the Dell, but it would connect to an Acer laptop and my desktop.

In any event I'm a bit relieved because I prefer the Dell when flying and renting a car because the Dell is small.

I had a similar problem with a USB stick... came to find out it was an intermittent voltage problem to the USB stick... sometimes it would work sometimes it would connect after sitting connected for about 20 minutes, sometimes it didn't do jack.
