Keeps displaying cannot get valid gps signal was working fine last week now does not work

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.

I had the same problem for past one week. I used "Tomtom home" application on my PC, connected my tomtom GPSusing USB cable to PC and downloaded the latest updates to the GPS. Now it works fine.

Yesterday my Tomtom XL took 10 minutes to get a signal. Again this morning and this afternoon. Just driven from Richmond to Ipswich and after taking a long time to get a signal it appeared to work OK. However many times along the route I noticed it had jumped from my route to parallel routes and eventually it lost the signal altogether and has not recovered since. Thankfully I knew where I was!!

Unit must at least have a partial view of the sky, or connected to an external GPS antenna that does.

It starts losing signal as the battery goes, maybe charge it and try to update it on tomtom home, also i had to same problem but now it seems to be solved with the update. does anyone know if the Traffic Reciever does any good?

My tom tom keep loosing signals should i stop purchasing the tom tombrand
