This sounds like a thermal issue. Maybe the lcd is overdriven and getting hot. To find out if this is the case, blow cold air on the receiver while it is running. If it stays connected longer than normal under these chilly conditions, then chances are that some component is overheating and shutting off. It will be most likely a transistor on the signal receiving portion of the board. In that case, I am sure that you will need to send it in to Garmin for repair. Good Luck!

No signal

you have to be outside or in a non steel covered building to get a good signal, i have found on my tomtom that sometimes it would scan for sats for 2 mins and nothing, then i would shut it off and restart and then aquire the sats, there is a time in spring and fall when the sun interfers with the sat signal and you wont get anything for 30 mins

I suspect that the power supply is not making a proper connection and comes loose in the socket, the gps unit then is forced to use battery power but since the battery is not fully charged yet when the battery power is to low the unit shuts down and will stay down till enough of a charge or the power supply gets bumped and makes a solid connection again.

Have Garmin Nuvi 660, after a few min. I lose sats. was working fine for the last year. Just the other day it started. I was in the mountains/ bad weather so I thought that was the problem. I have update...

Try this and see if it fixes your problem...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 try recover from the problem.

Receiver not picking up satalites

Sometimes it could take up to 10-30 mins with the GPS turned on and in a clear sky veiw , also not moving -like just laying on the porch or dashboard of a car to re-aquire sats and it datum table.

If that does not work, to fix the antenna would mean prying the unit apart to access the connection on the board.

Loss of signal after about 10 minn of time

If it happens around the same suburb the sattelite can't get to that area.

Or it is programmed for another location meaning : it wont display most of the places near you.

Or if its old it wasn't programmed with all the streets as new streets do get built alot.

Also this GPS is a pretty bad one as I am already dealing with 5 others They are all 660s and are the only GPS with problems.

Hope this helps - Josh

Gps loses signal

It would be good to make sure that the 951 software is up to date. The most recent software upgrade includes new code required due to changes that have been made to the GPS system. You can download the software for free from the Northstar web site but it requires a loader cable, power supply and a Windows based PC to perform the update. Most Noprthstar dealers know how to do this but they will charge for their time. The GPS antenna should be mounted where it has a 360 degree uninhibited view of the sky right down to the horizon to get best performance. Basicially any conductive material including pigmented paint, tinted glass or wet canvas can block the signal. Inspect the GPS coaxial cable and it's connections for any signs of corrosion or contamination. Sometimes just removing and reinstalling the connections is enough to remove contamination and get better performance. If in doubt concerning the coax and it's connections, temporaily substitute a new coax assy by-passing the existing cable to see if this makes a difference. You can monitor changes from the GPS status page. See the user manual for information concerning how to understand the numbers being presented. You should be tracking at least 4 SATs with signal levels higher than 30. Generally 95% of all GPS signal issues are related to the coax or its connections.
