USB port on Garmin Streetpilot I2

The USB port is loose in the case. Although I can reach it and plug in the cable, the unit does not work either because the cable is not going in all the way or the port is no longer connected inside the case. What tool is used to open the case so I can check this - allen wrench? torx screwdriver? what size? Thanks for your help.

Re: USB port on Garmin Streetpilot I2

If the USB port is loose, that means that the port has come of the circuit board. This happened to a friend of mines, his son did not look which way to orient the usb plug and used brute force. It will need to go back to Garmin for repair unless you are or know of an excellent solderer as the conenctions are minute. The case needs a TORX 6 screwdriver.

Have a six month old StreetPilot 7200 and the 12 volt cable stopped working. Unit apparently gets no power. Works fine with 120 V AC cable. Garmin says they have no parts for this unit. Is there a simple...

First, make sure that the unit really does run off of +12V. Most Garmin units really run off of +5VDC and there is a charger/regulator that reduces the +12VDC to +5VDC. Look at the power cable and see what the output voltage is. Does the unit has a USB port?

Recharging/Traffic Problem with Garmin StreetPilot 550


Initially, you would need a DVM (voltmeter) to check if there is an output from the cigarette lighter adapter/charger. Your post " lights on cable is on (the one closest to the socket)..." indicates that there is 12VDC coming in (from your car) but "...the other one is not..." signifies that the adapter is not processing the incoming 12VDC and forward it to your Garmin StreetPilot 550. With the DVM, you can measure the output B+ (which should be something like +5VDC) which is also the output voltage of your computer's USB port.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

I just bought a Garmin 265WT. I ran the registration program, but the computer does not recognize the Nuvi. I've checked My Computer and it does not show a new drive ( the Nuvi should like like a drive...


Try these steps:-

  • Unplug the USB cable from the computer.
  • Turn the unit off and then back on again.
  • Plug the USB cable into your computer.
  • The unit either automatically goes into USB Mass Storage Mode or displays USB Mass Storage Mode as an option on the screen.

Note: If your computer still does not detect the unit, make sure that you plug the USB cable directly into the computer USB port and not the USB hub. If the cable is already plugged directly into the computer, try plugging it into a different port.

Also, in some cases the operating system does not support the device. Try upgrading it to the next higher level. In most of the cases windows Xp service pack 2 does not recognise this Garmin device. Try upgrading it to service pack 3.
If you are still experiencing the problem then you will need to contact Garmin for repair.
Thanks for using Fixya.
Good Luck and have a nice day.

Battery on my garmin c510 sat nan wount hold a charge how easy is it to change

Had the same problem. Fixed with a new battery. Takes the same as a Streetpilot c530 and can be purchased anywhere on line. A 10 minute job with a soldering iron.

1. Open face plate. Unscrew 4 screws. Remove battery connector and clip.
2. Unsolder the wires to the two speakers - 4 wires.
3. Remove the sticky wrap from the old battery and place around the new one (to stop it rattling).
4. Solder back the new speaker wires.
5. Plug in battery, reassemble unit and charge Garmin off PC wih usb cable.

Unable to update unit

When you plug in the USB cable, if your System, Hardware, Device Manager lists "GARMIN Devices", then the problem has to be in your network connection or Garmin WebUpdater. If your Device Manager doesn't list "GARMIN Devices" then the problem is in the computer, USB cable, or 2720.

I have three 2720s right now with bad USB ports. I'm going to try replacing the USB driver chip in each unit, but now I'm just guessing. Hope this helps. Tom

Broken USB Connector (Garmin nuvi 200)

USB connectors are too fragile for the constant in-out service they get. But I have solved the problem, at least for standard Type A. The plug end (its steel case slips into the port end's steel case) is functionally female; it accepts the 4-pin tongue of the port and squeezes it between the 4-pin tongue of the plug end and the steel case of the plug end. So when the plastic tongues wear down, the squeeze isn't tight enough. Solution: take a small vise-grips and make the plug's steel case a little thinner, like a weight on a grilled cheese sandwich you're making. Then when you plug it in, it will resist a bit and feel tighter. And it will now work!

Turn on your garmin out of the car, connect to a PC via USB cable and see if the battery indicator goes away. If it does then the USB to PC cable is working and charging the unit. To test the car adapter, you can unscrew the tip of the plug to examine the fuse. Most Garmin car charger units have a light on them that ilimunates when you plug it in and turn the ignition. It could be that the plug is just loose in the socket. The picture shows the unit running on battery. If you plug in the usb cable and this indicator goes away, then it should be charging.

Windows XP will not recognize Garmin 200W

I had the same issue. I would plug it in and it would recognize the device then it would disappear.

What I did to solve the problem was to first turn on my Gamin 200w. After it was finished loading maps then I plugged in in to the usb port. My machine recognized the device without any problems. I am running Windows Vista Home Premium. Hope that helps.

The GPS is defective. Your usb/xm port is broken. You need to send it back to garmin.

USB port defective

Have you tried another USB cable? As long as it's got the same mini-USB connector, they are universal. Most digital cameras use these same cables, as well as many MP3 players and other handheld electronics devices.

If this doesn't fix it, most likely, it's a defective USB interface chip in the unit... and will need to be serviced. GARMIN 1-800-800-1020 (USA).

Fortunately, the USB ports on PC's are protected. When an overload is detected (> 500mA), the USB controller shuts down the offending port. This port can then be restored manually through the USB disgnostics, or simply shutting the PC down, and restarting it.
