Question about Garmin Nuvi 660 GPS Receiver

1 Answer

Just changed battery in nuvi 660 and now I have a very poor display. Like a computer screen with no video driver. Every thing was put back exactly as taken apart. Could it be the new battery?

No, one of the LCD flex cables is not fully inserted into its connector. unlatch the lock down flaps and reinsert the flex cables back in and lock down the flaps. Most likely this is a problem with the larger flex cable. If the screen lights, the smaller flex cable is OK. Its located to the right of the larger one in the center. The flex on the left is for the touchscreen.

My nuvi 660 turns on but displays "loading maps"


Hello,

The problem is that the nuvi 660 gps receiver is jammed and needs to be reformatted.
What you have to do is to disconnect the gps, and connect it to a computer, then format it.

After formatting it, you download the self extracting archive files for your nuvi on to your hard drive, then connect your nuvi to a free USB port on your PC interface cable and allow your nuvi to initialize and enter USB mode, Unzip the files by running the downloaded executable files, then follow the instruction provided by the launched update application on your PC.

Then install it back in your car and turn it on, it will work once again.

Take care and good luck
i hope this helps?

My garmin nuvi 660 touch screen dosen't work


To calibrate the touchscreen on a nuvi 300 or 600 series:
  1. Power the unit On.
  2. From the Where to? / View map screen, touch Settings (wrench icon).
  3. Touch Display.
  4. Touch Recalibrate.
  5. A new screen will display that says Press Dot.
  6. Touch the center of the dot.
  7. Keep touching the center of the dot as it moves around the screen.
  8. When Calibration Complete appears on the screen, please touch OK.
The touchscreen will now be recalibrated.

If your touchscreen is not responding to any touch and preventing you from recalibrating the touchscreen using the instructions above, please follow the steps below:
  1. Connect your nuvi to your computer with a compatible USB cable.
  2. Open the Garmin Nuvi drive located in MyComputer/Computer. (Note: Mac users can locate the Garmin Nuvi drive icon on the Desktop.)
  3. Open the Garmin folder.
  4. Locate and delete the GUPDATE.GCD file.1
  5. Safely disconnect your nuvi from your computer.
  6. Power the nuvi Off.
  7. Power the nuvi on by holding the power button.
  8. Continue holding the power button down for 1-2 minutes until the screen calibration option displays.
  9. Touch the center of the dot as it moves around the screen.
  10. When Calibration Complete appears on the screen, please touch OK.

The touchscreen will now be recalibrated and should respond properly.

HOW DO I INSTALL A BATTERY IN MY GARMIN NUVI 660


Replacing the nuvi 660's battery is actually not all that hard as this video demonstrates:
utube.png You-Tube video "S2KEu_if7wA" placeholder (do not delete) utube.png
The company that produced the video sells a kit which includes the battery and tools necessary to do this yourself if you'd like. See: http://www.newpower99.com/ProductDetails.asp?ProductCode=GARMIN+NUVI+660&Show=ExtInfo I swapped the battery of a friend's dying GPS using the aforementioned kit and all went well. His nuvi 680 is back up and running smoothly.

Screen is stuck on "garmin nuvi" and the on/off wont turn it off, and the device wont boot up.


It sounds like you have your gps plugged into your computer with the usb cable and that what you are seeing on the gps screen indicates that the gps has communicated with the computer. This is exactly what should happen. However, you cannot use your nuvi as a gps in this mode and you cannot turn it off and on.

Garmin Nuvi 660 shutting off


It sounds like your battery is defective. They can be replaced. The Motorola phone cable is not wired exactly like the Garmin, and your Nuvi thinks it's connected to a PC. Radio Shack carries a charger for the Nuvi. I have one myself.

Let me know if you need additional help with your battery problem.

Garmin nuvi won't turn on


folks, the garmins have an on-board battery that needs to be powered up (at least occasionally) via the usb port - like from your computer. just using the dc car power cord does nothing for this battery. i've had this exact same problem on both my 760 and 780 nuvi units. fixed it using the usb charge. seems to run down differently for all the various nuvi models. my regular charge will hold for 7 hours on my old 660, my 760 and 780 work about 5 hours. my 'power up' failed on the 660 after 10 months with no internal battery charge, but the 7xx models only took about 5-6 months to 'fail.' hope this helps. jack b :-) in midland, tx usa
