3590LMT Bracket

The 260, for example has the cord go to the unit directly.

If the manual says that that's where it goes, then it more than likely IS where it goes. But I just looked at the manual for the 3590 and it says that the connection goes to the bracket. I quote:

"Plug the vehicle power cable ➊ into the USB port on the mount ➋."

The model number really has little to do with whether the device has a powered mount or not. For example my old 350 has a power mount, but my 760 doesn't, while my 3790 does.

The mount for the 3590 appears to be the same as the 3790 in that it has a "speaker" in the mount. If that's the case then it is a powered mount. Garmin's website shows this for the 3590:

Voice prompts (e.g. "Turn right in 500 ft."): yes (internal and mount speaker)

Your 760 has a powered mount. And your sig is probably wrong too:

"Nuvi 350, 760, 1695, 3970T and TomTom 540s"

You claim to have a 3970T - not likely, unless perhaps you are beta testing one in advance of its release?

The 3590LMT power cord connects directly to the mount. The mount also includes the speaker.

No the 760 does not have a powered mount, at least my 760 doesn't. I have the 760 with the "cradle" attached in front of my as I type. The only connection is the USB port in the bottom of the 760.

I'll correct my sig.

What do you think all those pins along the bottom edge of the navigator and that big connector on the right side of the mount is for?

From the 700 series manual, page 3:

"Plug the vehicle power cable into the power connector on the right side of the cradle."

And I see you corrected your sig.

everyone for their reply.

I had a 760 and it most definitely had a powered mount with the car power cord plugged directly into the cradle and not into the 760 when it was mounted in the car.

Look down the page to figure 8 and the reviewer says and I quote:

"Figure 8: nuvi 760's Cradle, Front

Among other benefits, the cradle provides for quick docking/undocking of the nuvi from the windshield mount. Note that the 12v power cable connects to the cradle, and not the nuvi directly, so there's no need to fumble with the cabled when mounting or unmounting the GPS."

Thanks for that. I thought the 760 and 750 shared the same mount and my 750 mount is certainly powered (as is my 855's).

Wow, from your link with an October 31, 2007 date, check and see how far we've come: nuvi 760 MSRP $857; Street $799! And you still had to pay extra for map updates.

But on a positive note, 7xx users needn't worry about which JCV file they receive. [If your first nuvi was purchased in the past year, don't worry about the previous sentence.]

My own 765T has a powered mount.

@t923347
I certainly believe you that your 760 mount is not powered. Please double check the mount, the connector is recessed on the right side of the mount about 1 inch above the connector pins in the front of the cradle.

Did you by chance buy a used unit and the previous owner substituted a mount that would fit the 760 but is not powered?

Although higly unlikely, maybe it's posible that Garmin went from non powered mounts to powered mounts depending on the production dates.

I agree that I must believe what t92 says he sees.

But what's especially odd here is that the 760 was a unit that included traffic so rather than coming with a simple cigarette lighter power cord, it would have come with a (most likely a GTM20 in the USA although the European GTM21 and even the MSN GDB50 used the same plug and socket) combo power cord traffic receiver which requires an 18-pin plug on the mount to power the 760 and provide traffic.

Makes sense that a powered mount is needed for the traffic receiver. Now that I think about it about my statement that he may have a substitute mount could be wrong. The mounts are model series specific so I'm not sure a 700 series model was availbale without traffic.

We'll just have to wait for t923347 to get back to us.

Edited: Upon furhter investigation it appears the 750 did not come with traffic but was optional. So possibly it came with a non powered mount, To get traffic you would have to buy the GTM20 receiver and powered mount as a package. This is the only explanation I can think of.

There was only one mount that was available for the 760 and it was a powered mount. It is shown in the link below from the Garmin site. If you look at the photo you can see the connection in the side where the power cord is connected to the cradle. If you click on the compatible models tab you will see the list of the only 8 specific models that the mount will work with.

A good thought which would explain things but that's not the way Garmin sold the 750.

I purchased a new 750. It came with a power-accepting cradle and cigarette lighter power cord that connected to the cradle:

https://buy.garmin.com/shop/shop.do?pID=1371

I later bought a used GTM20 traffic/power cord receiver and it replaced the above power cord connecting to the stock cradle that came with the 750.

It appears that all nuvi 7x0 models came with a power-accepting cradle which in turn powered the nuvi--and the cigarette-lighter cord was either power-only or power/traffic depending on the model purchased. That's why I'm so confused about t92's results. His 760 defies my explanation because it has a non-powerable cradle and a USB-ended power cord rather than the 18-pin Garmin connector that all Garmin literature says the 7x0 series had.

Confused I am.

If he bought the 760 used the prior owner may have kept the more expensive traffic receiver cord or sold it separately and just included the car power cord that comes with a cheaper non powered cradle model. Those cords would plug into the GPS USB port instead of the cradle and would power the unit and not really use the cradles connections at all. The non powered cradle models use the USB connector and are not nearly as wide as the traffic cord and do not have the locking tab release on them that locks the cord into the cradle.

Still can't figure this out since you say the 750 had a powered cradle.

It is a possibility that t923347 was mistaken which is not shameful, I make mistakes every day of my life and will continue to do so. Hopeuflly he will get back to us with some more details and end this suspense.

The mystery is: was there ever an option for a non-powered cradle for the 700 series?

Didn't know that non powered cradles were available for the 700 series. The power chord are readilly available but he said te has the cradle in front of him and no power connector. So that must be the answer and he is correct in his statement.

He might not recognize the connector on the cradle as a power connector because it is long and very narrow and designed for a specific power cord with the same style and is designed to lock into place. It does not resemble the USB connector at all that is on the 760.

I do not think that the non powered cradles would even allow a 760 to attach to them.

This is a large pic of the only cradle that will work with the 760 and you can clearly see the longer and narrower power traffic cord connector in the side of the cradle:

Sorry, I hadn't checked this thread since yesterday afternoon and didn't realize that it was going to keep going and going.

Anyhow, I apologize, the mount is powered. I don't use it in the vehicle anymore and only use the cradle to hold the 760 on a bean bag mount I use in the house, beside my computer. In that configuration I just attach the wall charger to the USB port on the Nuvi and never attach anything to the cradle.

It wasn't until I looked for the actual vehicle cable this morning that I realized from the connection on it that it could only plug into the cradle. Once I looked, I did find the power connection on the side.

Thanks for getting back and solving the mystery.
I enjoy a challenge but this had me stumped.

We can now put this to rest since we now know all 700 series only come with a powered mount.
