Lose of signal in inclement weather

I have the old nuvi250(one of the first gps's on the market).
I am concerned about signal disappearing on my set as I go through
a snow storm.
I recently lost signal from the sun in the summer,I believe they call these solar flare-ups.

Mike, this is not uncommon. These units work like all other products that produce signals to a given satalite. In some cases as many a 8,9,+. Also your signal will come back. Last but not least, the position and/or place you place your unit also makes a difference in some cases in getting good signal strength. Hope this helps. Blessings, Season Greetings.

How to download australian maps onto nuvi250 with south african maps


Hello,

It is never recommended that you install the maps in the unit, there is a slot in the unit for an SD card you will have to install your Australian maps to an SD and insert them into the GPS.



Hope this helps!

Garmin Nuvi 255 - no separate feature to delete individual addresses. I go to tools - my data - delete favourites - the only choice I have is to Delete "ALL". There is no edit feature. There...


GPS SYSTEMS HAVE A TENDENCY TO LOSE CONNECTIVITY TO SATILLITES BECAUSE OF BAD WEATHER, CLOUD COVER, TUNNEL ENTRANCE, BAD OR NO POWER, BATTERY LIFE HAS BEEN EXPENDED, HAZARD OF ELECTROMAGNETIC INTERFERENCE TO GPS SYSTEMS, AND IMPROPER VEHICLE MOUNTING AND HAND HELD POSITION. FREE SOLUTIONS 1. ALWAYS PLACE YOUR GPS DEVICE IN THE UPPERMOST PORTION OF YOUR VEHICLE SO THAT THE GPS SIGNAL MAY EASILY LOCATE YOUR DEVICE EVEN WHEN THE WEATHER IS BAD 2. KEEP YOUR BATTERY CHARGED ONLY WHEN IT NEEDS IT MOST AND AVOID CHARGING OFTEN 3. IF YOU OVERCHARGE YOUR GPS DEVICE, YOU WILL EXPERIENCE BATTERY LEAKAGE, WHICH CAN EAT AWAY AT YOUR CLOTHING, DESTROY YOUR DEVICE IN SECONDS, AND CAUSE DAMAGE TO YOUR VEHICLE SEATS 4. YOUR GPS DEVICE HAS A TENDENCY TO FREEZE BECAUSE OF THE SIM AND MEMORY CHIPS LOCATED WITHIN IT 5. YOU CAN FIX THE FREEZING PROBLEM BY REMOVING THE SIM CHIP AND MEMORY CHIP AND RESTARTING YOUR SYSTEM 6. OTHER FREEZE PROBLEMS OCCUR BECAUSE THE DEVICE IS COLD WHEN IT IS KEPT IN THE VEHICLE AND CHIP CREEK OCCURS WHERE THE DEVICES MICROCHIPS BECOME LOOSE AND TIGHTEND BECAUSE OF WARM AND COLDER AIR FLUCTUATIONS. IT IS BEST TO KEEP THE DEVICE IN A PURSE OR ON A TABLE WHERE IT IS NOT SUBJECT TO CONSTANT TEMP. CHANGE 7. PREVENTION OF ELECTROMAGNETIC INTERFERENCE IS BEST SOLVED BY: interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common

What would cause a linksys g 54Mbps router to give a signal of 54Mbps, then slowly drop to 24?


distance, Make sure you are well within range, That happens alot if you move around, also remember that it's wireless, if you have inclement weather it may take its toll,
But usually when that happens its a connection issue, you could try unplugging everything modem router and then restarting it all up, Sometimes its just fuzzy.

How do i find my product key for my nuvi250


Hello,

The Garmin product key, also called the product serial number, is included in the box your Nuvi i250 comes in. This number is nine digits; it's printed on the yellow specification sheet. Fortunately, the key is also printed on your Garmin unit, which is helpful in the event you lose your specification sheet. The Garmin product key is required to register your Nuvi i250 with Garmin. (Registration allows you to download software and map updates, and receive recall information.)

Follow the procedures below on your nuvi i250;

  1. Turn your Nuvi i250 around to view its back.
  2. Flip up the GPS antenna with your finger. Look behind the GPS antenna for the specification sticker.
  3. Write down the nine-digit product key. With this number, you'll be able to register your Garmin. (See "Resources.")
Good luck

Device is locking up and losing satellite signal at times


Are you sure there IS a signal all times? Especially when driving in cities with tall buildings or near transmission lines the signal may seem to 'disappear' and the screen freezes.

Lose of signal


This is not always an easy fix.
one has to know whether you are trying to run a GPS in a city that is overshadowed with trall buildings, a forrest like set of streets where trees overhang and obscure the sky.
Then there is the low battery level that can cause loss or no signal, or the windscreen that is so sloped it does not allow sky view.
Some cars have other electronics installed that cause interference, finally the GPS itself.. TOMTOM, one of the worst GPS on the market for failoure. and problems. Just trawl through FIXYA and see the number of TOMTOM requests for help there are to any other brand

here are some solutions.

make sure battery is fully charged on AC charger before usinjg. connect it to DC car power after engin hjass been started to prevent spike damage to chip.

fit an external mouse antenna, not the cheap and nasty types thyat only raise 28 decibels
contact Marbella Australia for their 50Decibel antenna its the best on the market and only available from them . .
place Gps closer to your windscreen for a better view of the sky.
keep away from other electronics like mobile phone radio etc to see if it works better.

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.

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.
