It can take 20 minutes or more to download the almanac and ephemeris from the GPS satellites. Just give it time.

Says loooking for signal - even when plugged into car charger - could it be the gps battery


Being plug into a car charger (or wall charger) has little to do with not finding a GPS signal and this apply to your gps battery as long as you get power to your receiver.

It is not unusual for GPS to have problem finding suitable Satellites signals especially inside a building or areas where you do not have a clear view of the sky above you and the unit (e.g. High Rise buildings).

In order to speed up the location of satellites signals, you need to update your unit A-GPS Satellite locations database on a regular basis via 'Tom Tom Home' (which should be installed on your PC or Laptop). You can download the latest version of Tom Tom Home from the official site.

Without A-GPS and the unit not being in regular use, your unit may take a very long time to find suitable satellite signals. My own TomtOm One, without an up to date a-gps database has taken over 15 minutes to locate the required signals even in a relatively 'open' air location!

Hope it helps and clarify the issue.

I lose satellite connection every time I turn on my GPS unit. After few minutes connection will be restore by itself. Why this happing and what can I do to fix it. Frank


If you shut the unit down - and remove it from the power cord in your car, this is expected.

When powered down, the unit is not capable of maintaining contact with the satellites in the sky. When you power it up, it needs to receive signals from 3 or more satellites get a "fix" or calculate your position in the world. The more signals received, the the more accurately displayed your position will be. The device must use the signal data, perform calculations and bring up a map of your area.

The "Lost Satellite Reception" message also occurs whenever the GPS does not have a clear view of the sky over the earth's equator. This can be from a garage roof to heavy foliage (tree cover) - and even when driving between tall buildings. Usually, it shouldn't take more than a minute or so (once the obstructions have been cleared) for the GPS to reacquire the signals, calculate and display your new position.

I hope this helps!

No valid GPS signal for two days, what I can do?


You can try a reset Check in the manual where the reset hole is i thinlk this model is under the scfreen surround which is removable.

This will take ut back to factory settings, you might want to check if its set to the right PORT and BAUD try this

GPS Program Port: COM1
GPS Hardware Port: COM9
Baud Rate: 4880
Manage GPS Automatically (Ticked)


Now other reasons are low battery= low signal//fully charge the battery


no signal from satellites= damaged SIIRF chip caused by plugging into car power when starting engine...needs new m/board

Maximum time to access 1-9 minutes max...




Please rate my help++++Thanks for using FIXYA...

Why does my GPS system have a difficult time locating satellites?It says ''acquiring satellites'' for about 5 minutes. Then it says it can't locate satellites. Should it continue trying? Why does it do...


this is what my navigon says about gettting the gps to connect.

Initializing the GPS receiver
In the upper right-hand corner of the display, the GPS symbol appears. As soon as
data from at least 3 satellites is received, the symbol changes to (GPS Ready). Note: If possible, position the device with a clear line of sight to the sky to successfully
receive messages from the GPS satellites.
Note: GPS initialization requires data from at least three satellites. If GPS data is not
available, the receiver will not initialize.
Note: It can take up to 20 minutes to initialize the integrated GPS receiver for the first
time.
Note: Each time you turn on the device, GPS receiver initialization begins. When GPS
data is available, reception starts within one minute.
If the navigation device has been switched to standby for more than a week, the next initialization
can take up to 10 minutes.

Magellan roadmap 760


The Magellan 760 has been around for a few years now, and unfortunately, isn't one of the fastest units around when it comes to synchronizing to a satellite. I find with mine that the time it takes to lock onto a signal depends on several factors:
1) Having the GPS mounted in a way that allows the antenna to have a clear view upward 2) Having my vehicle in the open, so that the signal isn't impaired by adjacent buildings, overhanging trees, etc. 3) Being stationary while the GPS attempts to get a lock. It has more problems locking while moving. 4) Ensuring that the GPS is used frequently, as it loses its memory of what satellites it's synchronized with if you happen to be in a different place when you turn it on than the place you were at when you last turned it off.
Those last two points have the most affect on my GPS's performance. I find that by turning on the GPS and just parking in my driveway or parking lot for a few minutes will allow the GPS to acquire a signal in a much shorter time than if I start to drive immediately. While this will waste a bit of time on the front end, it does help you get synchronized more quickly

Quest not receiving signal


The antenna socket has probably become unsoldered - follow this writeup for more information.

Garmin Quest is out of whack


Hello, I currently own a Garmin quest myself, and some time ago I had some strange problems myself, I am a electronics technician, and I do have a work around for you. I will explain the problems and a cure for you to try, none of the work arounds depend on any parts to be removed.

1. NO RECEIVING SATELLITE TELEMETRY. I beleieve this could be due to a number of reasons, but more so at sometime corrupted telemetry was the problem to fix this,
a turn GPS on when booted (initialised)
b. depress menu
select settings
select Time Setup
when in Time Setup depress MENU
Select SET DATE
Depress OK button
Depress OK button again on the numberic keypad that appears on the screen (DONE)
what this seems to do is resets the internal date/time clock and the unit starts to work again.
the Second workaround is this but takes hours to perform.

Simply turn the Guest on and allow the battery to fully discharge, usually this works to TOTALLY flush the Memory again, but on my unit I have to setup all the maps again, this is easy to perform, but just takes time. I hope this helps you.
