My tom tom one xl has worked fine for a year,now all of a sudden no gps signal,satelite indicater is 0. Battery is FULLY charged. Please help.

The TomTom device needs to tune in on three or more GPS satelites to find your position. On start, it scans the hemisphere for any satelites and ten minutes and more are not uncommon to establish fixes on them.

The solution is a data package you can download from TomTom servers via the Home software, "QuickGPSFix". It holds precomputed satelite positions for the next few days which speeds up locking to satelites to a few seconds from minutes. However, you need to update the package roughly once a week or the initial delay will pop up again.

If it will not stay charged then the battery is defective, these type of batteries have an average life of 2 years, less if they are run dead allot, more if they are left on the charger and kept fully charged between uses.

There are two things you should know.
1) is that the battery must be fully charged in order to connect. The car power is insiufficient to FULLY power the battery. it is maintenance charging.
2) Starting the engine whilst the GPS is plugged to car supply kills the SIIRF chip. Then no connection with satellites is ever possible again.

If you have done this resetting to factory settings or flying into a rage will not fix it

It will require a new motherboard, as chip replacements are uneconomical.

TOMTOM do not advertise that spikes may come from the starting of the engine and claim that a fuse protects it from happening. Well hahaha I have made a living from fixing their boards as a result. It does hap[en and often the fuse is not compromised.

It should ttake the maximum of 9 minutes in some situations to lock on to satellites if the battery is low it can take longer But never hours! A well charged up battery will lock on in an average 2 minsts if outside with a clear view of the sky. there are 20 channels up there so all you need are just 4 for a connection.

Thanks for using Fixya.

OK Heres what to try.

1) Check the BAUD rate and PORT are set in accordance with the manual
2) the battery is fully Charged ( AC)
3) a clear view of the sky.

If all of those are as they should be then it may be a damaged SIIRF chip which makes it a throw away item. Cheaper to buy a new GPS

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.

You essentially have to reset the GPS. You can do this by holding the power button down for at least four seconds to get the Tom Tom to fully shutdown. You will know you successfully did this if you hear the tom tom sound and a warning message appears during startup. It then seems to work just fine after that.

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.
