When I switch my 670 on it finds the satellites and works fine once I begin to move it switches to Acquiring satellites and the ? symbol appears. If I switch to the satellite indicator it shown no connection. If I then switch it off and on again it occasionally works OK for another 2 - 10 minutes. I have tried a re boot but it has no effect.

Re: After 2 - 10 Minutes Satellite connection is lost
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 above problem.

When you turned it on in the hotel, it is not the Garmin. But if you were outside and could see the clear sky, and the GPS evice did not find the satellites within 2 minutes there could be something wrong.
When you switch of an GPS in one place and you switch it on, on a completely different place, it can take a while till it found enough satellites to make up where it is.
But two minutes should do the trick. Don't try this somewhere inside or close to buildings or trees. The device should have a clear "view" to the satellites above the equator.
With a normal GPS device, when you first switch it on, it needs some time to locate enough satelites. Most of the time it needs at least 5 satelites. Some time should be like minutes and not hours. After the GPS device fond enough satelites, it knows where it is and can when it is switched on again work faster. When you try to let the GPS search for satelites indoors, or without a free view to the sky, it is possible the receiver never can find satelites at all. I don't know if any test of the Lowrance iFINDER Hunt GPS was placed on the net, but that is where you can check how long it should take for the GPS to find enough satelites.
If it is a new unit it can take up to 30 minutes to find the satellite for the first time. I suggest connecting in your car and make sure it is charging and leave it on while driving to work or running errands. If it has been working and now it is not try pressing the reset button
Turn the Garmin Nuvi 1300 off.
Press your finger against the
bottom-right corner of the Garmin display screen. Leave your finger in
place as you power the unit on.
Release your finger when the
display screen asks, "Do you want to erase all user data?" Use your
finger to tap "Yes." The unit will begin to reboot. Do not use the unit
until the main menu is displayed. The reset process should take about 45
Once you get it going; go to the Garmin website and update the unit. Thanks for using FixYa
Experienced the same problem in 2006. I left Trinidad and was in Germany. My solution, turn on the GPS outside and had to wait about 20 minutes before it started acquiring sattellites. had to do the same when I returned to Trinidad
You need to perform a reset. Not sure if this is 100% correct for that model but you press the menu button while sliding the power switch. If that's not right it should be in your owners manual or contact Garmin tech support for the exact way.
When you do this have it plugged into the power somewhere, preferably outside or someplace it can or should see the sky. Once you reset it, set it down and walk away from it and do not touch it for up to an hour. It will reset itself wiping out its satellite data which obviously has a problem. Now it will find a satellite and download a new catalogue of satellites which should take a minimum of 15-20 minutes and up to an hour. Once it has that it will find itself and should be operating normally. So when you come back to check on it it should show it finding the satellites again. At that point go ahead and use it as you normally do. It's fixed.
If that doesn't work you probably have a failure in the receiver section. So you will need to get hold of Garmin and find out about warranty repairs or replacement. These are usually pretty bullet proof so hopefully its just the GPS not having the correct data.
If its raining, that will cause you to lose satellite reception.
If that is not the problem, then do this: turn off TV & satellite. Wait 5 minutes. Power back on. Most of time this will fix it by itself.
If neither of those do it, unattach your satellite cable from back of satellite box. Power everything off. Wait 5 minutes. Now reattach your satellite cable. Power everything on. It should search for you sat and find it. Let me know if this works.
If none of those work, then I would call the sat company for help.
Satellite tv cannot work thru regular splitters so make sure if u are using one it is a good one . Check all your connector to make sure there is no little wire touching the coper one , then try moving your dish while someone is checking the signal intensity in front of the tv . If u do all of this , im sure ur gonna get it working in no time
I have been experiencing the same problem many have been
having with the Nuvi 6xx and 3xx series giving an error message “Lost satellite
My problem started mid April 2008 and got progressively
worse. I would use my GPS on weekends and it would work perfectly for the first
10 – 30 minutes and then would loose satellite reception, rendering it useless.
I bought my Nuvi 660 when it first came out in October 2006
for just under $700 and is now out of the 1 year warrantee.
I called Garmin Technical Support and we checked my Software
version (4.40) and more importantly my GPS SW version (3.00). According to the
tech I had on the phone, the GPS SW version was more important then the Software
version. It was in fact already updated to 3.00, I did master reset, after
master reset, but regardless, nothing helped.
I contemplated what I should do.
Return mine and get a refurbished unit from Garmin for $225
with only a 90 day warrantee?
Buy a new Nuvi 660 for around $300
Buy a new Nuvi 2xx series with fewer features for $200 to
Buy a Megellian GPS?
I read through this forum and came across one person that
was told by Garmin “that they are aware of an issue with some Nuvis involving
the failure of a diode in the unit that senses whether or not an external
antenna is connected.” Apparently this diode failure is caused from the high
heat these units experience from being left in a hot car for long periods of
time. This would explain why mine would work in the beginning and then die.
So my thinking was, if the diode “thinks” there is an
external antenna attached when it isn’t, what would happen if I “did” connect
an external antenna?
Garmin recommends the Garmin GA 25MCX low profile remote GPS
antenna for the Nuvi 660 and costs $31.49 (not sure about additional costs for tax
So I purchased the NEW antenna from a seller on eBay for
$25.90 total and IT WORK FLAWLESSLY.
Just to make sure it really was the new external antenna
that was working and not the unit coming back to life, I started my 3 hour
journey with the external antenna NOT connected. As usual it lost satellite
reception in about 15 minutes. I plugged in the GA 25MCX and it immediately connected
to the satellites and never lost them.
I repeated the same process coming home and once again, I connecting
the external antenna after the unit reported loosing satellite reception, and
it worked perfectly.
Conclusion: if your unit is experiencing loosing satellite
reception, and is under warrantee, return it ASAP. If it’s out of warrantee,
get an external antenna. There are other manufactures of external antennas and
all should work as long as it has an MCX connector.
Side Note: This external antenna also worked perfectly on a
friend’s Nuvi 350 with the same problem.
I wanted to share this with everyone because I’ve been
racking my brain for months over this. I hope this helps.
