Yesterday my c580 was loseing sattelites constantly, it wuold either say "POOR SATTELITE RECEPTION" or "LOST SATTELITE SIGNAL" did aybody else had the same problem yesterday, was it something going on with the sattelites or my unit broke? Any ideas?
The GPS cannot acquire a satellite position, in part because it doesn't show any satellite signals. The unit has worked well unitl three days ago. Now, it is problematic. Eighty percent of the time, it can't acquire a signal. Then, when it does get one, it loses the signal during the route. Does it need to go back to the factory, or is there a setting I can adjust?
I had a similar problem a month after I got my 660. It was stuck for a day. I would start it up and it would load the map where I was and then get the poor reception message and the map would stay frozen.
Tech support tried to do a reboot etc. and gave me a choice either to ship it back and get a refurbishes, or give a credit card number and ship it back and get a new one.
In my case it was a defective unit.
When you say a new one, you mean they wanted you to buy a new unit? What did you do?
I have had a time or two where my c330 would lose the satalite signals for a few seconds but it would come right back. Never the 80% that your talking about.
They wanted to make sure I sent back the first one.
Rather than wait and get a refurbished, I let them charge my credit card for 800 bucks which they credited back upon receipt of the defective unit.
I don't have the problem your discribing but once in awhile I will get poor reception do to the armored booth I sit in much of the day(I like to mess witn my gps while at work).
I get this message only everytime I go through a tunnel. Otherwise, never gets this problem
I had the same problem when I drove through Rocky mountains in BC this summer.
My 670 started losing signal when it was about a month old.
Sent it into the local Garmin dealer and they replaced the aerial. Since then it has worked fine.
I sent my unit to Garmin for repair, hope they'll fix it
I used an external antenna on my recent trip, and it worked excellent (~20 dollars). Even going through a very long tunnel in Colorado on the I70, it kept tracking fine.
I usually have this problem when driving in canyons, but funnily enough, I noticed that over the thanksgiving weekend, the gps was having more difficulty than usually in trying to maintain a signal.....I was curious if the number of users accessing the satellites (via their GPS unit) has anything to do with it....
No - the satellites send the same signals regardless of who is receiving them. The gps units aren't transmitting data back and forth with them.
I could be wrong, but I seriously doubt that it maintained a signal through the tunnel. More likely it knew that you were in a tunnel and it estimated your speed and "simulated" the car going through the tunnel. i have seen that happen quite often with mine.
Asianfire-The option you just said is the Dead Reckoning feature. Nuvi doesn't have that so it will not doing what you described.
I could be wrong but why don't you check if there is any new firmware available for your unit. I have Nuvi 770 and after the update it grabs the signal within a minute. Before the update it took 10 min to 1 hour.
Ummm...that is good to know what it is called, thanks!
I just don't see how someone (including myself, cause it has happened to me) can get a signal through 5 feet (normal thinkness of an underwater tunnel) of concrete and many feet of water. It can't be coming from the two ends either
