Question about Garmin Nuvi 660 GPS Receiver
I'M USING ALL CAPS SO YOU CAN READ MY RESPONSES TO YOUR INSTRUCTIONS.
WE HAVE FOLLOWED YOUR ADVICE FOR RESTORING SATELLITE RECEPTION BELOW, TO NO AVAIL. WE GET THE ETERNAL MAP OF GARMIN HEADQUARTERS UNTIL THE UNIT TIMES ITSELF OFF, AT LEAST 30 MINUTES LATER.
(BTW, WE DID ALREADY DOWNLOAD THE LATEST SOFTWARE)
There are a few things you can try to restore satellite reception.
1. place your finger over the lower left-hand corner of the screen and hold it there while pressing the on/off power button. Keep holding your finger there and a window should pop up asking if you want to go into maintenance mode. Select yes. There is an option called "clear user data". Select that option. It will not erase your favorites.
It will however, erase any corrupted satellite data and will default you back to some factory settings. This will clear some of the memory allowing your Nuvi to collect new satellite data. Your Nuvi should reboot and it will ask you a couple questions like, timezone, language. Please select the proper settings. Make sure the antenna is up and that you are outside. On the main screen, you will see a satellite bar graph in the upper left-hand corner. Touch the bar graph and you should get a satellite map, showing the satellites. If your Nuvi's receiver is working ok, you should see horizontal hollow bar graphs appear on the right. Eventually they will turn
solid blue. This indicates they have downloaded the proper data from the satellite. When you have (4) solid blue horizontal bars (4 satellites), you will see the top panel begin to show improved accuracy and your Nuvi will then work as it should. This entire process make take 30 minutes or less.
If you don't see any bar graphs, your Nuvi may ask you several minutes later, if you are indoors. If your outside, select no. It will then ask you if you have moved 1000 miles since your last use. Select yes. This will cause your Nuvi to start looking for satellites, trying to locate your new position. When you perform a factory reboot, your Nuvi thinks it's in Kansas (Garmin HQ) and so it needs to be told to look for new satellites.
Now, if you still don't see any bar graphs, then your antenna may have a problem. There Is a known issue with the Nuvi antenna where a part has failed, causing the Nuvi to no longer use its internal antenna and it's now always looking for an antenna at the external antenna port (the gold connector on the side of the Nuvi antenna). If you have a piece of small wire, a couple feet long, you can insert that into the center lead of the
external antenna jack. Most likely, you'll begin to see bar graphs after a few minutes
and your Nuvi will lock.
WE DID THE WIRE CHECK AND IT DID NOTHING
Here's another way to determine if your antenna has failed and will have to be replaced: At the main menu, pres on the "wrench" symbol. Then press the "gear" symbol and then press "about". There is a field marked "GPS S/W". There should be a number next to it. It may be "2.9" or "3.0". That is good. That tells you that the main board in the GPS is communcating with the antenna receiver.
WE DID THE CHECK AND IT SAYS 3.0
Please let me know if I can be of further assistance to you.
PLEASE GIVE US SOME SUGGESTION HOW TO GET THIS $800 TOOL TO WORK AGAIN. THIS IS THE SECOND ONE THAT FAILED, FIRST ONE WAS DURING WARRANTY, THIS ONE IS BEYOND THE 1 YEAR WARRANTY SO GARMIN JUST WANTS US TO SEND IT IN WITH $225.
THANKS, ANXIOUS TO HEAR FROM YOU
Iwas able to "fix" my Nuvi 660 by simply jumping the external coaxconnector to the internal antenna. The fix is detailed by ernesas here:
Heincludes a photo of the circuit board with instructions. (Note that itis the second photo on the page, not the first one!) The downside tothis quick and easy fix is that you will probably lose external antennafunctionality. I never used an external antenna so no big deal.

Try this and see if it fixes your problem...first disable bluetooth then follow these steps.
1. Power off the unit.
2. HOLD down the power button and you will see "Pre Boot Mode" appear on the lower part of the display. KEEP HOLDING the power button down and the display will flicker, do this until the pre boot mode message disappears. This seems to take a long time (60 seconds at least).
3. Once the pre boot mode message disappears release the power button and your device will perform some activites to recover from the problem.
