Top 10 Garmin Nuvi 660 GPS Receiver Questions & Answers

These are the instructions I got from Garmin as how to do the Master reset:

Here are the steps to backing up the favorites on your unit and then performing the master reset. First, you’ll want to plug your unit into your computer via USB cable. Once it’s plugged in, you’ll want to go to My Computer in your start menu or from your desktop and double-click on the Nuvi. At this point, you should see a few folders, but you’ll want to double-click on the Garmin folder. Here, you’ll want to look for the “GPX” folder and you’ll double-click on that. In this folder, you’ll want to drag and drop the file titled “Current.gpx” to your desktop to copy it. Now you are able to do the master reset.

To do that, you’ll want to start with the unit turned off and press and hold on the upper left hand corner of the touch screen. While holding the touch screen, power the unit on and continue to hold. You should get a message that asks if you really want to go into maintenance mode and you’ll want to select “Yes”. At this point, you’ll want to select “clear user data” and then select “Yes” when it asks you if you really want to clear user data. Now, the unit should restart and you’ll want to take it where it has a clear view of the sky and let it sit for up to 30 minutes to acquire satellites. If after 30 minutes it does not acquire satellites, you can go ahead and reply back to me.

Either way, once we have your unit back working again, you can follow the first set of steps again to get to the GPX folder and drag the “Current.gpx” folder from your desktop to that folder on your unit. This will replace your favorites.

Please see this article I wrote on this problem.

The ribbon cables are clameped in place. The look like they would slide out from the connector if you pulled then hard enough,... you do NOT want to do that. The black portion of the connector is actually a hinged clamp. With the unit lying on a table, face up as it you were using it; lift the top screen half away for the bottom half and tilt it toward yourself. You should see the ribbon cable and the red & blk wires. For the wide center connector and the one on the right, the black piece hinges up an away from you (towards the top). Try the one on the right first. When you flip it up, the ribbon will pretty much fall out. Pry the wide center one on the ends, NOT in the center. The narrow one on the left tilts donw towrds you. For the antenna, the hinged peice is brown, and it flips up towards the right. This one does not just fall out. It needs some gentle wiggeling. Also, I was able to use a T6 torx, T5 seemed a little loose,... yo don't want to strip any screws or you'll be screwed. SpaceVector

Note: This is for a 550c Street pilot

1) Turn on unit
2) Press VIEW MAP
3) Press SPEED in lower left hand side of map
4) This will bring you to the Trip meter screen on this screen press the round speedometer at the top of the screen for about 10 seconds this will bring you to the SYSTEM BIOS.
5) From this point forward be careful you can mess up your unit by changing the wrong thing.
6) Press NEXT until you come to the BLUETOOTH STATUS screen.
7) Now press UPDT P this should complete your update.

I have de solution:
*pick a torx 3 tool
*release de equipment
*put on 22 awg copper cable in the main chip on upper right pin and touch softly the + pole of a 3V batery.
tested in a garmin nuvi 780

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

Is the battery charged? What does the battery indicator say? If you are using it in the car, is the power cord connected and working properly? If it is working correctly, you should see a lightning bolt symbol over the battery bar graph showing that it is connected to an external power source and that it is charging.

Guys and or ladies... I know that you have to create a folder named "GARMIN" in the sd card so the maps can be recognize. Maybe this solves your problem. Let me know if it works.

I discovered a recently posted video showing how to change the Nuvi 660's battery. I purchased a battery from newpower99.com and they took care of me well. My little "surgery" went smoothly with their kit.
