Antenna out of position?

• How to Reboot Your Satellite Receiver

Instructions

1. • 1 Check the TV and make sure the channel is set to 3 or 4 for the primary TV set, or channel 60 for the UHF (secondary) set, if the receiver is a "dual-mode" device.
     
   • 2 Check all connections on the back of the receiver. Make sure all cabled connections are tightened and all plugs are securely plugged in.
     
   • 3 Check for a key card loaded in the card slot on the receiver. If you have a key card, slowly and carefully remove the key card. Leave the card out for at least 30 seconds, and then re-insert the card.
     
   • 4 Unplug the main power cord from the back of the receiver. Wait at least 30 seconds and then plug the power cord back into the receiver.
     
   • 5 Press the "Power" button on the front of the receiver to power on the device. Allow the receiver several minutes to acquire a signal and download any additional updates. The receiver is reset.

It might mean that the signal is disrupted. Might be a software glitch. Try going outside, get a clear view of the sky. Then reboot/reset the unit. Hold the switch to the reset position or off position for 10 seconds, it will shut off. then switch it back on. It should reacquire a signal within 2-5 minutes, then it will fix on your position. If that doesn't work, try updating your software. Call Magellan Tech Support for instructions.

Usually, when it's waiting to get a valid GPS signal, it is "listening" (scanning) for satellite signals to establish your current location. If you are in the open outdoors, i.e. not inside a building or under extended covers, it should get the satellite signals within a minute or so.

Usually, after you turn on the GPS device, it may take a minute or so to start up and lock into the satellite signals. While it is waiting to get a valid GPS signal, it is "listening" (scanning) for satellite signals to establish your current location.
If you are in the open outdoors, i.e. not inside a building or under extended covers, it should get the satellite signals within a minute or so.
If you still can't get a GPS signal, consider shutting it down ... using a "hard" shut-down (hold down the on/off button for 5 seconds or more ... to re-boot the system/software programs. Then, wait a while before starting it up again. Make sure your device is plugged in and/or the battery is NOT low when you're doing this.

It is possible that the LNB is not tuned to the right slot to track the signal from the source sattellite. So use the right direction to set the parameters, set the dish to the required direction.
If the signals tracked are free channels then you must receive them.
So keep trying to get the dish in the right orientation, get signal after coarse setting and then fine set for tracking the signal without signal splits.

Press and hold the antenna signal strength icon on the display to bring up Satellite reception information. This will show you what, if any, satellites are being tracked. It will also tell you if you're in DEMO mode, in which case real satellite signals won't be used for the position.

Additionally, you can check the hardware by using the built-in hardware self-test features by pressing and holding the battery icon. Examine the information presented on multiple pages by pressing 'next'. Look for the hardware TEST button and press it. Wait several seconds for results.

These two steps should at least tell you where the problem is. If you ARE getting Satellite signals but they aren't being used by the hardware, you may need to reset your unit. Also check for firmware updates by using the Garmin Update utility available on their web site.

The most common problem to this is because the TomTom doesn't know it's current location.  It may be that you last used your device a long distance from where you currently are now.  I don't know how long you waited for the gps signal to acquire but it can take up to 10 minutes (even on military aircraft if they don't know current location).  
Power it up and press on the signal strength icon.  That will bring up your satellite tracking status.  If it don't look like it's doing anything, then your gps has probably malfunctioned.  If it looks like it's acquiring satellites, then give it a good amount of time (10-15 minutes) to see if it can find your location.  I recommend doing it outside of your vehicle with no satellite obstructions to make the process go faster.
Good Luck

Turning off WAAS and then "Super Master Reset" (then reacquiring signal normally) did the trick for me. Note that it will wipe out ALL saved waypoints, so write 'em down before trying. This link describes it:

FYI ....My Roadmate 760 would not aquire a signal, I went to diagnostic screen and found it was detecting/tracking 0/0 satellites. Held the plugged in unit out the window and within 10 seconds was tracking 7 satellites! Turned out my 1999 Olds Silhouette Van has a anti-glare filter inside the factory windshield that blocks GPS signals.My wifes 2001 Chevy Impala also has same type filter. Check your windshield, filter is visible inside glass to within about three inches of edges of glass. Worth a look.
