Garmin Vista Slow To Acquire Satellites


Recommended Posts

We own two GPS units and we had both of them with us today. We turned both of them on and let them get a lock on our location. Then, as a test, we turned them both off and on again in a few minutes. The Gecko sprang to action and determined our position in less than a minute. The Vista picked up and lost satellites and after 5 minutes still had not located our position. Both had WAAS enabled and were set the same way. Is there something I'm missing here? Is there a reason for this great disparity in function? Do I have to upload new software to the Vista? It is several years old and the Gecko is much newer. I always use the Gecko because it is so light to carry. It is a bit harder to read the digits, but I really like it. If it didn't have dumb games built in it would be near perfect!

I was caching friday and we had 2 etrex yellows and 1 vista. The guy with the vista was having trouble locking on after standing still for several minutes. We started walking towards the trail head when I turned on the second yellow and it locked in less than 30 seconds.

I would update the firmware on the VISTA -- unless you have the newest already. Could it be that the Almanac data needs to be acquired??? Try leaving the Vista stationary for 30 mins. or so locked on -- maybe it will get more data so it can lock-on easier.

 

Other than that, Antenna may not be as good on the Vista (or faulty).

I agree with Bozz on both accounts. Over the years I've had several GPS units get stubborn. A good 30 "baking" in clear view of the sky with a good constellation always seems to work.

Update the firmware, reset the GPS, then leave it sitting out for 20 to 30 minutes out in the open. If i turn on the gps a minute or so before driving from the house, it will not get a good signal for several minutes, because of the movement of my position, and the GPS's switching of satellites as i drive. This creates a poor satellite lock. Ive done it so many times. So the best solution is doing an initial lock after resetting, in a stationary position, for up to a half hour.
