Question about Garmin nuvi 1490T GPS Receiver

1 Answer

I have reset my Garmin using the 10 hold several times. It only gets to the screen saying Garmin and loading maps. It still will not simply power on and off. It will only come on or turn off after holding the power button for 10 seconds. I have a MAC and have downloaded the necessary plug in and webupdater applications in order to update my garmin. Using the Garmin USB cord, for some reason the garmin is not being detected and I am unable to update it. All that appears when i plug the garmin into my computer is a black screen saying Garmin with a small green vertical line. Why is my Garmin 1490 not being found when it is plugged in? and Why is it not turning on and off without resetting it every time?

Device hangs up when loading maps.


Try performing a soft reset of the nuvi 1310 by holding the power button for at least 10 seconds until the unit powers up.

A hard reset can also be done.
To perform a hard reset :
Note: A hard reset will erase all waypoints or Favorites and will restore your unit to the default factory settings. If you would like to back up your Favorites to your computer, you can find instructions to do so here.

• Start with the unit OFF and unplugged from power
• Press and hold the lower right corner of the screen
• Continue pressing and holding the lower right hand corner of the screen then power the unit ON
• Release the power button when the device powers ON
• You will see a new message: Do you really want to erase all user data?
Remove your finger from the touchscreen when this message displays
• Touch Yes

Also, be sure that the nuvi 1310 has the latest software update by installing and running the Garmin WebUpdater program.
Load or reload the latest software update as this will usually resolve most issues.

You may also want to contact Garmin Support for assistance.

Have you tried resetting the unit, by holding the power button for 10-15 seconds. I had a similar problem, and it actually required two steps to fix it. Simply holding the power button for 10-15 seconds would restart the unit, but it would shut down again during the "Loading Maps." part of the boot process.
So, do this. Hold the power button for 10-15 seconds until it appears to begin booting. See if that takes care of it. If it still doesn't work, plug it into your PC and let it get to the state you described. Then unplug it from the PC, and see if it reboots on its own. If it still isn't working, then hold the power button again for 10-15 seconds.
This worked for me.

Borrow a USB cable to plug it into a computer. I just had this issue with the nuvi 1300, and that was the only way to fix it.
Holding the power button for 10-15 seconds would attempt to restart it, but it would just get stuck on the "Loading Maps." section.
I was able to fix it by simply plugging it into a PC's USB port, where the unit started up for purposes of data transfer. Then I unplugged it, and it restarted properly.

Will not load maps and says charging when not even plugged in

There are three levels of getting your Garmin 255W's attention and correcting bad habits (ie: not loading maps or locking up).

The first is 'soft reset'. There is a reset button along the bottom of your gps. Push and hold it until it restarts. If you cannot locate your reset button, sliding the power switch to OFF and holding for 8 seconds should do the same thing.

The second method is a 'hard reset' or 'clear all user data', to restore factory defaults.

The Hard Reset procedure has been known to delete your Favorites, so back them up beforehand.

  1. From the Nuvi drive, copy '/Garmin/GPX/current.gpx' to a backup location on your computer.
  2. After the hard reset, copy your backed up 'current.gpx' from your computer back to the '/Garmin/GPX/' folder on the Nuvi, but be sure to rename it 'temp.gpx'.
  3. On the next power cycle, the Favorites will be read from 'temp.gpx' into the non-user accessible memory area on the Nuvi where they are actually stored.
Perform the Hard Reset:

*Note that this will clear all user selected settings on the unit

  1. Power the unit off.
  2. Remove the battery and wait several minutes.
  3. Install the battery.
  4. Press and hold (and continue to hold) the bottom-right corner of the screen while powering the unit on.
  5. Continue to hold the screen until the "Do you want to erase all user data?"prompt appears.
  6. Press "yes" and the unit will reboot. This resets all your location settings and user preferences.

The third method is a firmware upgrade via Garmin's Webupdater, or the myGarmin site.

Run through these fixes to get your Nuvi running as good as new.
I hope that helps.

Nuvi 200 will power up - comes up to a screen that says Garmin - loading maps and then goes off again. Any help with this?

Sounds like it has a corrupted map file. If you have a memory card take it out and try it. If that doesn't get around it then try a system reset. Press the reset button on the bottom or hold the power switch on for about 10 seconds to reset it.

If none of those get you going its time to call Garmin. They have excellant support and a toll free number. Usually any problems I've seen on Nuvi tend to be from add on maps or running it over with the truck or it going for a swim but other than those they just work ;-]

Touchscreen not responding.

There are three levels of fixes, please try them in order:
1. Reset the GPS using the Reset button, on the back, just under the Antenna Hinge. Resetting will turn off the GPS, and then turn it back on, if connected to power. Test, if fixed, great, otherwise, go to fix 2.
2. Turn the power off, then press and hold the powerbutton for up to 2 minutes. The GPS will turn on, and display a "PreBoot Mode" message. When that message disappears, and the screen calibration screen appears, follow the on-screen instructions, and you are fixed. If you still cannot use the touch screen, repeat fixes 1 and 2 several times, just to be sure., then go to fix 3
3. The touch-screen glass has probably broken or lost its connection with the GPX motherboard. You can order new touch screen glass on the web and install yourself, if you are techy in nature, otherwise do a search for "garmin nuvi 660 repair" and choose your service.

Can not get route information desoite having had it programmed into garmin

Try doing a hard reset. Hold down the back button (leftside), the thumbwheel, and then the power button. This will reset all setting back to factory default. You will lose any custom setting, recent find and waypoints.
