It doesn't find a satellite signal - Tomtom ONE XL GPS

Sounds like a bad wireless card or the card slot.I would try replacing the wireless card.When wireless cards go bad they either cause the laptop to not boot,low or no signal reception or the card isn't seen at all by the motherboard or operating system or .both.If it isn't showing in device manager either with a caution sign or installed the card is most likely bad

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.

it is more useful when you always include brand names and manufacturer names on every device you need help with.. anyway if it is a motorola than go here: http://www.acs.nmu.edu/faq/index.php?action=news&newsid=23&newslang=en

Mine actually stopped working the same day you posted this. How strange is that? I have not been able to figure out what is wrong with it. Have you figured out a solution?

This indicates that the antenna is not gathering enough of the signal to be played. This can be caused by an obstruction between the antenna and the satellite in the sky ie: tall buildings, heavy tree cover, covered garage, etc. It can also indicate a problem with the antenna itself, the cable between the antenna and the radio, the connector on the end of the cable or in the radio or, a problem with the antenna circuit inside the radio.

Since there's little you can do about the last item in the list, check the other parts of the antenna for damage. A pinched or crushed cable will short out the antenna signal - and the voltage sent to it by the radio. If allowed to persist for very long, damage to the radio could result. Look for breaks in the outer jacket of the cable - water entering the cable will cause corrosion and will degrade the signal, too. If you find a problem with any part of the antenna system, about the only thing you can do is replace the antenna completely. You can get a replacement online for as little as $9 and change.

Before installing, try connecting the antenna to the radio with the antenna exposed to ta clear view of the sky in a location that you were able to receive a signal before. If it works, you're done. If it doesn't - the problem is internal to the radio and will need to be repaired - or replaced.

I hope this was helpful - if it was - please rate it "4 thumbs up" Thanks!

Correct. Like all satnavs it needs a fairly clear and unimpeded view of the sky in order to connect with the satellites. The signals from the satellites are incredibly weak and so it doesn't take much to block them out.

Tree cover, tall buildings, deep gulleys and similar will reduce accuracy and location refresh rates or even prevent them altogether.

Looks like your set is not receiving the signal from the sat. receiver. Make sure that the audio/video cable is in good shape and connected correctly, then select the correct input on your tv. If that doesn`t work try to connect a dvd or vcr on the same cable, if that is still no go then you may have a bad audio/video cable or there is a problem with your tv set. If it does work(dvd/vcr) then you`ll have to check your satellite receiver. Hope this help. Good luck

This is a problem with weak signal strength, You will need to find a better place to put your television so it can receive enough signal to operate correctly. If this does not solve the problem, you will need to check the satellite box for problems with receiving the signal from the satellite. You may need help from the satellite company to check the signal strength output and input levels to make sure its working properly. I hope this information helps you solve you problem with the loss of satellite signal in your television. Thank you for using FixYa and have a nice day!

It may simply be trying to load the almanac and ephemeris from the satellites. This can take up to 1/2 hour with a strong GPS signal outdoors.

Your dish is out of alignment. The local channel satellite doesn't have as strong of a signal, so a slight misalignment will cause problems.

It could also be an F-connector needs to be replaced at the dish or multiswitch (if you have one). Sometimes moisture builds up inside the connector and corrodes the copper stinger inside.

If you go into your satellite signal strength menu and find the local channel satellite, you're sure to see either a weak signal or an intermittent one.

One more thing, if a tree has grown in the line of sight between the dish and the satellite, this will cause signal problems too. In this case, you either have to trim the tree or move the dish.

Hope this helps!
