GOOD MORNING OVER THE LAST 2 DAYS I HAVE HAD ALMOST NO SATLITTE SIGNAL? WHY I TRAVEL ALL OF FLORIDA THE TOM TOM ONE XL I HAVE IS A GREAT UNIT BUT RECENTALY THE SIGNAL IS ZERO FOR HOURS AGAIN WHY

Try resetting your TomTom.
To reset your ONE XL, use a straightened paper clip, or something similar, to
push the reset button. The reset button is next to the memory card slot on the
bottom of your ONE XL. Then turn your ONE XL on.
I have attached the link to the manual which shows a picture on how to do it.
Thanks for using FixYa

1- Signal strenght loss is a common problem, has to do with how often they refresh, whats on your dash and how good the line of sight is to the gps sattelites. Ironically the window mount that they give you can in some cases place the gps unit too far back from the window to get good clear reception.
2- You are out in the field because of the maps that you are using. Maps while mostly accurate are not exact and road changes that are made to sections of road may take years to show up in the map or might never show up. There are only two or three actual companies that do the gps survey work for the roads, and gps manufacturers like Tom Tom buy user rights to use these maps, so if a particular section of road has changed or been moved and nobody has been out to recalcute the changes then your gps will be off the mark.
Hope this information helps you out.

It is most lkely the battery, chane the battery and recharge it. batteries collapse after about 2 -3 years depending on use and abuse. If you have it plugged in when starting the engine the battery will deteriorate quicker and eventuslly fail. resting the battery can cause some charge to return, often sufficient to run it for short periods before it once again fails due to output being greater than the chrging rate.

i work as a truck driver on a small fleet of 7 vehicles in the midlands UK

3 of us have Tom Toms, the others have medion, navman or garmin.

ALL the tom tom users have been experiencing GPS problems this week ( june 21 onwards ) whilst the rest of us have seen no change in GPS satelite availability.

In addition, a friend who uses a TOM TOM One XL in another part of the UK has also had same problems.

Its a TOM TOM problem generally it seems, and NOT your particular piece of kit.

Try going online at the Tom Tom site and updating the device (it's free). There's a new update each week that tells the Tom Tom where the satellites will be during the coming seven days. Admittedly, this only speeds up the process and not finding a signal for 200 miles is a stretch, but it's worth a try if you don't regularly update.

GPS units are rather conservative in their time of travel estimates, allowing for driving equal or less to actual speed limit. This can end up giving you an extra hour or two. Mapquest is the same way if you used it pre-gps. Tom-Tom now has IQ Routes Editions that will analyze actual travel time of routes by you and other drivers, take into account time of day and conditions, and give you more accurate driving times.

I have a raymarine C80 three in one GPS,Radar,depth sounder....no signal or scanner from radar on sreen it has power.

I suddenly lost the GPS signal today and could not get it back. All I got was the "No valid GPS signal". My solution was to tap on the GPS satellite bars when in the route map. this brought up the "Status summary page of the TOMTOM.

I then again tapped the satellite bar which brought up the "GPS Status" page. I then tapped the bar labeled "configure".

The radio button next to the option titled "Minutes (dm.m') was selected. I then moved the selection to "Degrees (d.d) and it started working.

I had just downloaded the GPS fix 5 days ago so it is not like this suddenly caused it to stop working.

This may not work for everyone but this is what it took to get mine working.

Cheers

Try to reset the device. I used to have a Tom Tom 500, which has the same problem. 

I talked to TomTom support about recharging. They say that the unit uses more power than it gets, but if you turn the power off while the car is running, it will recharge.
