Re: usb port trouble

You may have to run the program with administratve rights. (I had some trouble after getting a new laptop with Vista, that fixed it).
It may also be a faulty port on your gps, or a breakage in the usb cable... Or it may be broken...

Will not turn on

Hi Larry -

Your Nuvi 765T should light up when you connect it to your computer's USB port. If it doesn't, there may be a problem with the USB port. Try connecting to the other USB ports on the computer (or a different computer - such as one at work, etc.) if needed. This will help rule out a defective USB port on the computer. You can also connect to a USB charger for another device that you may have instead. It may not charge with another product's USB charger if it provides a very low power output though. The auto plug will not charge the Nuvi when it gets into this condition. Even if it does not light up, leave it plugged into the USB charger / or port over night.

Check the GTM20 traffic receiver plug. It has two LEDs on the body. The one closest to the power cord end is the Traffic Reception Status light and the the one closest to the plug end is the Power light. If either of these lights is on when connected to the Nuvi, the fuse is good. If not not, you may need to change out the fuse in the FM traffic receiver plug. The plug powers both the traffic reciever and Nuvi. Carefully spin off the bright metal ring to disassemble the end to access the fuse. Replace if it is open / blown. If you need replacement parts, they can be purchased from Amazon for about $6.

After charging over night via charger or USB port, disconnect the nuvi from the power / USB cord and turn on by sliding AND holding the power switch in place to turn it on. Keep it held in position for 10 - 15 seconds before letting it slide back. During this time, the Nuvi should start up.

If it will not power up, the battery may be unable to accept a charge. You can replace the battery yourself, but it requires a steady hand, jewelers tools, good eye sight and patience from people selling parts to do this on eBay for as little as $6. Here's a link to those auctions.

If you'd prefer not to do the work yourself, a second option would be to let Garmin handle the "repair". Your 765T is likely out of warranty, and garmin offers a "flat rate repair" fee of $99. If you opt to do this, you will send your 765T to garmin and they will send you a different 765T that has been factory refurbished; complete with the most recent maps available already installed and a gaurantee good for 90 days. Not a bad deal when you consider the cost of upgrading just the maps one time on the 765T. You can start the process on garmin's site, linked here. I have used this service myself and was quite happy with it.

I hope this helps & good luck!

Where do I find the serial number for the Garmin NUVI 1490T?

if you installed the mapsource software go to 'transfer' at the top, and recieve from device, or send for that matter, while the gps is connected to the computer by usb and turned on the serial number will show up as the device in the little box.
if you don't have map source installed it's in the software, go to system and configuration settings it's there somewhere you may need to poke around a little.

I have a Magellan Roadmate 2000. I now have a small computer with no CD Drive. I forgot to transfer my Magellan software to my new computer. I am disabled & need this desperatly. Can you help Please?

is your computer up to date with updates. if so, shut the computer down and restart it, then ck if it will see your 2000 if it doesnt, theres nothing in those cd that will help you. if that fails try updating your usb drivers, you can also try another port on your pc if you havent already. i have a qosmio that acts up sometimes and wont see any of my units till i restart the computer.

Garmin 305 will not send info. to my computer

It sounds like the PC has possibly lost the driver for the Gamin. Back up your files on the PC and reinstall software.

How do I charge my Magellan 1412 with my pc?

i read your manual , and it doesn't specifically state it will charge thru the usb cable , but most do , usp port on pc having 5 volts , is handy , they may or not have given your unit that option , i all can say is leave it plugged into the usb when it is dead or low and test it sometime . don't kill the messenger :)

Garmin GPSMap 60 CSx USB Connection

Actually, I just solved the problem myself...

I went to Garmin's driver download site ( and got the latest USB driver (2.2.1) for the 60C. (Although, it appears that that driver pertains to all Garmin products, not just the GPSmap series or the 60C.) Installation instructions are pretty much standard for Windows drivers, so it's easy.

That: a) Garmin requires special USB drivers for their product is finicky (most USB-connectable products just connect automatically using Windows' generic USB driver), and b) my unit -- which had always worked just fine, and suddenly stopped connecting out of the blue -- remains a mystery. Nonetheless, a driver upgrade was the final step that I needed. (Although, I also swapped USB cables and upgraded MapSource, too, so maybe it's some combination of those things.)

Trouble connecting to any computer


Make sure your using a USB cable, specifically a USB cable with a mini connector on the end. Specifically, a USB cable with the second one from the left in this picture:

If you are using the USB port, you should have no need for setting COM ports.

Another technique you can use (which I just figured out today) was to place the Garmin Unit in "USB Mass Storage Mode". This allows you to offload saved tracks, but I don't think you can download waypoints or other things that the WayPoint Manager allows.

You can access this option via the Garmin Unit

Goto: "Main Menu" -> "Setup" -> "Interface". Press Down to get to the button "USB Mass Storage". Plug in that USB Mini cord, and you have a thumb drive!

Good Luck!

No communication with computer

I would try downloading the USB driver from magellan (if they offer it).  You may also be able to get the driver from C-Map USA as the do the map software for magellan.
