The GPS device needs to have a clear path to the sky to get the 2-3 satellites needed to pinpoint your position. If you travel through tunnels, etc. the signal will be blocked.

It *might* be
- that the "CMOS battery" (normally a coin cell about 13mm in diameter) is dead, in which case you should replace it.
- The crystal which stabilizes the RTC has drifted.
- If this problem has always occurred it may be the that the RTC chip is defective, but this is highly unlikely, and even less likely to have developed a fault with time.
- if you connect to the internet frequently (several times per day) the above can be ruled out (I think).
It may shutdown when it gets too hot. Toshiba Satellite had some problems with this a few years back which involved a class action lawsuit. I had one of the computer that experienced problems and lost a lot of material which had not been backed up yet. I received compensation as part of the class. The lawsuit was settled, but I notice that the Satellite that I purchased since then will shut down automatically when it gets too warm. It helps to put it on a cooling device and I also turn on a regular fan and point it toward the computer when I can. If it is inconvenient to do any of this, I turn it off periodically to let it cool down. That way, I don't lose any data. Of course, I back up all data frequently.
Just a few weeks ago Sirius XM changed there channels. That might have been one problem. But it shouldn't be loading all the time. It might be losing the channels and have to reload the channels.
Your problem might be that the GPS can't get a lock on the satellites and it doesn't know in which part of the world it is.
I suggest you download the latest updates and QuickFix, then leave the unti close to a window (even if you are indoors). The unit should be able to get a fix on the GPS satellites in less than 15 minutes.
Please, let me know if you need more detailed instructions
By the way, TomTom suggest to update your GPS at least once a week. This ensures that the GPS can finde the satellites quickly. believe me, after I did it the 1st time, the GPS was able to find the setellites in less than 10 seconds. Most GPS take a good couple of minutes :)
I can help you fix the satellite problem with your Garmin Nuvi 265WT.
Poor satellite reception, loosing satellites, and taking a long time to acquire satellites are issues that have been addressed by Nuvi 265WT firmware updates.
There are three steps to take to get your Nuvi 265WT running better than new:
1. make sure the unit is as low un the windshield as possible, remember it needs to see the sky, the more sky it can see the more sat it can lock in on.
2. Check the GPS Mode, under tools(Wrench), select system, the GPS mode, make sure it is in the normal setting. WAAS is more accurate, but most of the sats are at the equator, so in some areas the coverage is not as good.
Hope this helps.
Hello jacke328, In order to maintain satellite connection your GPS receiver needs a clear view of the sky. If you are operating the GPS in areas where the view of the sky is limited due to tall buildings, hills and mountains, or dense forest, your GPS is liable to lose signal from one or more satellites and this can impact the receiver's ability to determine your current location. If you are operating the GPS inside your vehicle an external antenna may help significantly. The body of the vehicle can act as a shield, blocking the GPS's ability to receive satellite signals. This is why most manufacturers recommend installing GPS receivers on the dashboard with a clear view of the windshield as this maximizes the amount of visible sky. Installing an external antenna on the vehicle and connecting this to the GPS can help significantly, however. Depending on the geography of where you are operating the GPS, you may have to live with an occasional loss of connectivity.With proper mounting you can minimize this, however.
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.
