Re: Navman 510 keeps losing GPS signal too often.

The antenna may be unplugged. You can check by removing the SD card, carefully unscrewing the four screws from the back of the device and then running your fingernail (NOT a screwdriver) around the seam on the case to split the two halves. The antenna is the small panel on the back of the receiver, it plugs into a computer board on the inside of the receiver. Look inside for a gold colored connector, it should be plugged into one of the boards, if it is not then that's your problem, you need to plug it back into the board and you should be in good shape.

My Golflogix keeps on searching for satellites. Using it for the first time, do I need to be on the course?

No, you do not need to be on a course for it to acquire satellites, however new units sometimes need to be left outside with clear sky view for up to 30 minutes to fully acquire signals.

We keep loosing contact to the sattelites. Is there a way to reset it, so we get a constant signal?

Mine did the same, and said no gps no fix. I called the factory, now called Northstar, tech said to reset unit, and it worked. Great signal strength. Turn unit on and access menu, access factory settings,hit factory reset. However you will lose all your waypoints.

Satelite reception lost constantly

Hello sothypaw,

In order to receive satellite signals your GPS receiver must have a clear view of the sky. If you are using the GPS inside of a vehicle the body of the vehicle may shield the unit from receiving these signals.

To minimize this the GPS should be mounted at the lowest place within the automobile that has a clear view of the windshield and side windows. If you continue to have problems then you might consider purchasing an external antenna for use with the GPS.

Even with a properly mounted GPS you may occasionally lose satellite reception due to local terrain (hills, mountains, dense forest etc.) or other obstructions (parking garages, tunnels, etc.) which can block reception.

When i put my Navman icn 320 on sometimes it takes upto 30 to 40 minutes waiting for the GPS signal to come through

Hello adamant,

In order to determine your current location the GPS needs to receive telemetry information from several GPS satellites. In order to do that it needs a clear view of the sky. This should happen fairly quickly, typically within a few minutes, but depending on how and where you are operating the GPS the process could take significantly longer or the GPS might be unable to aquire a satellite lock at all.

Local geography such as mountains, hills, tall buildings and heavy forest can block the GPS's ability to receive satellite telemetry. The same thing can happen if you are trying to operate the unit indoors or inside of a vehicle without an external antenna. That's why most GPS receivers are installed on the dash board of the car: the windshield and side windows provide it the best view of the sky.

It is also possible that there is a problem with the GPS receiver or the antenna. To test it, try using the device outside in a relatively open area with a clear view of the sky in all directions. It should aquire a satellite fix in about five minutes or less.

I am losing satelite connection frequently. Sometime for a few seconds and sometime for up to ten minutes

Hello jacke328,

In order to maintain satellite connection your GPS receiver needs a clear view of the sky. If you are operating the GPS in areas where the view of the sky is limited due to tall buildings, hills and mountains, or dense forest, your GPS is liable to lose signal from one or more satellites and this can impact the receiver's ability to determine your current location.

If you are operating the GPS inside your vehicle an external antenna may help significantly. The body of the vehicle can act as a shield, blocking the GPS's ability to receive satellite signals. This is why most manufacturers recommend installing GPS receivers on the dashboard with a clear view of the windshield as this maximizes the amount of visible sky. Installing an external antenna on the vehicle and connecting this to the GPS can help significantly, however.

Depending on the geography of where you are operating the GPS, you may have to live with an occasional loss of connectivity. With proper mounting you can minimize this, however.

My garmin nuvi 200w sat nav keeps losing the gps signal. I've done a manual reset and used the webupdater to ensure the software is up to date but still it keeps losing the gps signal

There are a few options for you...
1. Check to see under what kind of conditions the GPS loses it's signal. If there are tall buildings, is a cloudy day etc or even the position of the GPS in the car (does it have a clear sight of view of the sky)... In the latter case, you could change the position of the GPS where it gets a clear view of the sky. For Cloudy days, better have a map ready or preplan the route using mapquest/googlemaps, as nuvi 200 series is especially notorious for these type of situations. For tall building problems, what I do is (c330, not nuvi), just tap the route displayed on the top before the signal gets lost and memorize the next few upcoming turns. Or avoid downtown (where those huge skyscrapers are)
2. If you have enabled WAAS setting in the settings menu (it should be somewhere under "GPS mode", disbale/uncheck it and use the normal GPS mode. WAAS may provide you a more accurate position, but at the expense of some avaialble satellites.

3. Or your GPS may have a genuine problem, then your only recourse is to call Garmin and talk to them. Here's the contact info:

1-888-442-7646 (U.S.)
1-866-429-9296 (Canada) or (913) 397-8200

Good Luck. Personally I would avoid the 200 series and go with the 3xx, 6xx or even better the 7xx series (if you need all the bells & whistles)

Garmin NUVI 650 acquiring satellites

  • Make Sure the GPS has a good, clear view of the sky. “Clear” does not need to be sunny. Overcast skies have no noticeable impact on GPS performance. But buildings and trees do. So take the GPS outside where you have the biggest sky view as you can.
  • Next, wait for the GPS to acquire a signal. If this is the first time you have used it, expect it to take up to 20 minutes to find a signal. Most often it will take less, but prepare for 20 minute. Now for an important step… Once it has found your location, let it continue to sit there for about 30 minutes.
