I had this problem - couldn't acquire satellites even on mountain top with clear skies. Cobra said unit was defective, so returned for refund. Seems to be a common problem with these units.

Regardless of which GPS unit you use, finding sufficient satellites can be difficult if you are working in an area with trees/mountains/hills or other obstacles. Here are some suggestions to locking onto satellites:

1.) Mission Planning. If you think you're going to be working in a tricky area, but sure to check mission planning. This software allows you to input a location and obstacles, and gives you the times when satellites will be best.

2.) Wait. It takes the GPS units varying amounts of time to "find" satellites, but if satellites are visible, the unit should lock on within 5 minutes.

3.) Move. If possible, move into an area that has a clearer view of the sky.

4.) Face south. This is especially important if you are using the GeoXT. Turn the GPS antenna so that it is facing the southern sky. The majority of satellites have their orbit so that they appear in our southern sky. There are also satellites in the east and west, and almost no satellites to the north.

5.) Rotate around. If facing south doesn't work, slowly rotate the GPS around 360 degrees.

Updated unit and still acquiring satelites is showing, what can i do?


If your unit is still acquiring satellite, then it means the signal strength is weak, try to get it outside where it can be facing the sky directly so it will be able to acquire satellite. Once you just update your gps receiver, it seems like it is brand new and when it wants to first acquire satellite, it might take longer to do so. But if it has access to the sky directly, it should take about 3 to 5 minutes to acquire.
If your unit is indoor, it may not acquire satellite, even if it is close to the window, it will not, but if it is outside, then it will acquire faster.
Check if you have any protective coating on your windshield or electronic devices which interfere with the unit from receiving signal from the satellite. Try to see if your gps receiver can use an antenna, then connect one to it and your gps will acquire satellite.
Try to reset your gps first before trying any other solution for the unit.

Why wouldn't my ifinder h2o c gps not pick up any satalite signal


The most common reasons are thus
1) You do not have the right PORT and BAUD set
Consult the manual for the software.
2) You are noit in a location where the sky is visible to the unit)
move outside and away from buildings or electrical items
3) Your battery power is too low to get a fix

4) nThe SIIRF chip is damaged

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

296 takes forever to acquire satalites.


If you don't use it very often it can take time to find its location. Have you tried using the 'set initial location' option? Once it knows roughly where it is and what time it is it can then work out which satellites it should be looking for instead of searching for any/all of them. The manual does say that it will take time if it has no initial clue as to where on the planet it is, and if you're on the move while it's trying to work that out then it may take even longer. Obviously, if it has a poor view of the sky, or if most of the satellites are behind you and you have a tin roofed aircraft then that will probably not help either.

Initial gm-510 gps has intermittent gps signal and loose antenna


well a loose antenna can cause intermittent connections, but so can a low battery, despite it being plugged into a power source. Make sure battery is fully chatrged before use. I would suspect the battery chage first. Even get a new battery

I am not getting satalite signal on my tom tom xl


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

tall buildings in the cbd reflect satalite signals causing incorect fixes. an ext antenna helps a little bit.

GPS screen went blank


My problem exactly. Unit would start up, acquire satellites, then the screen would go blank with a single vertical line. Unit would not respond to buttons or even turn off. Unit works fine after I did the reset:

- w/unit OFF, press and hold QUIT+DOWN+MENU
- press and release the power button, release DOWN, keep holding QUIT+MENU for 5 seconds.
- unit prompts something like: "erase all data;" choose yes.
- you will lose waypoints, etc.

Go to the Garmin support area for details.
