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

Hello there,
As GPS units are used, data is gathered which helps them acquire satellites quickly at the start of each use. If a device is used daily it should be able to acquire satellites in a minute or less. Using a GPS device while it is outdoors with a clear view of the entire sky is the ideal condition for acquiring satellites. Please know that there can be several different factors that may cause a GPS unit to not acquire satellites:
If your unit is trying to acquire satellites for the first time, it may take longer than normal to establish an initial position. If the unit is powered on and outdoors with a clear view of the sky this should not take more than 3-5 minutes. If your unit has not been used for an extended period of time (more than a month), it may take 3-5 minutes to acquire satellites. If your unit is indoors, it may not acquire satellites. Even standing next to a window indoors will block a majority of the sky which is needed for a device to locate and lock onto a satellite signal. If you have just finished updating the software in your unit or you have performed a master reset, your unit may take 3-5 minutes to acquire while outdoors as the data that is used to locate satellites may have been erased. If your unit has traveled over 500 miles while turned off or not tracking your travel, it may take 3-5 minutes to acquire even in ideal conditions. If your vehicle has a protective coating on its windshield or electronic devices which interfere with the unit receiving signal, your unit may need an external antenna* in order to acquire satellites. If you suspect this to be an issue, try taking the unit outside of the vehicle with a clear view of the sky for 3-5 minutes so that the unit can acquire satellites. If your unit loses satellites once moved back into your vehicle you will most likely need an external antenna*. If your unit is still having trouble acquiring satellites, please ensure that it has the latest version of operating software by using our WebUpdater program. Once your unit is updated please allow the unit to acquire satellites outdoors in a stationary position with a clear view of the sky.
*Note: Some units may not be compatible with an external antenna. Please check the Compatible Devices tab on the external antenna's page to see if your unit is listed.
Hope this was helpful to you. Goodluck Elect_Comp

Good Luck

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

If its raining, that will cause you to lose satellite reception.

If that is not the problem, then do this: turn off TV & satellite. Wait 5 minutes. Power back on. Most of time this will fix it by itself.

If neither of those do it, unattach your satellite cable from back of satellite box. Power everything off. Wait 5 minutes. Now reattach your satellite cable. Power everything on. It should search for you sat and find it. Let me know if this works.

If none of those work, then I would call the sat company for help.

Are you outside with a clear view of the sky? It should find satellites once the unit is turned on. Does it say "Looking for satellites" or "Acquiring satellites"?

If it is "looking for satellites" then it means that the unit have lost all data (time, date, location). If it is "acquiring satellites" then it have date and time, but not location.

Looking for satellites require a longer setup time (could be as much as 15 minutes). Acquiring satellites is much faster (not more than 2 minutes).

Date and time is updated from satellites once the unit gets a satellite lock.

open up your unit, careful when opening as the RF cable will be tight in between the boards. make sure there is nothing banging around in the unit.. (shake it and listen).. if yes then investigate and report back. if no, then make sure all the cables you can see are tight. especially concentrate on the RF cable.. long cable.. either black/carbon fiber or grey cable. One more place to check is your antenna, (which you'll have to take off before you open up your unit, so do this first) yea jut make sure the antenna is on the unit tightly. Also try resetting user data. + and repeat button at user menu, then select reset GPS data. -Daniel
