Its also possible that if you have changed your vehicle, the new vehicle might have a special type of windscreen heated windscreens or heat refective which stops the GPS Signal getting through to your unit, I had the same problem, but seems to work now, i know its not the unit, the same symptoms also occured with a different unit in the same vehicle. if you think its the windscreen you can buy a ariel which allows the tomtom to pick up the signal.

This problem can have several causes.

  1. A component fault on the units internal antenna circuit board.
  2. ribbon cable has become detatched inside that connects antenna board with main circuit board.
  3. A software fault.
  4. A component fault on the processor board.
All the above except number 3 will require proffessional investigation. if its a software fault then you may be able to recover data by a re-install through TomTom Home or by recovery backup ( you did make a backup of your SD card , didn't you ? ) of your SD card.

I have a Tom Tom One N14644 Ver 8.014 that displays "No valid GPS signal". I used the GPS to get to an address the other night, and now it gives me a map, screen choices, but says waiting for valid GPS...


Same here. I just finished updating software and it still can't get a signal. Could it be something with the TOM TOM satellite network?

I have the same unit and version as you. I notice the problem started yesterday at about 5:00 EST

Waiting for a valid gps signal


A couple solutions:

1) Make sure the TomTom can "see" the sky well... the GPS satellite waves are rather weak and easily blocked by trees, and anything not a window.

2) Hook up your TomTom to the computer (see details at www.tomtom.com or in the manual)

2b) Do a "sync" and download all updates. One of the updates is a small file that tells the TomTom where the satellites are located this week, and helps it sync up much faster. The longer time between uses, the longer it takes TomTom to find the satellites, and that can takes up to 2-5 minutes sometimes.

That can be frustrating with a car full of people waiting to get going and the driver doesn't want to drive without making sure the TomTom works and is giving valid directions.

Tom Tom sat nav takes ages to get a GPS signal now.


Think I have sorted the problem out. I read some of your readers' solutions and it was mentioned that it may be advisable to log onto the GPS update. So, I installed my disc which came with the pack and followed the instructions to download the GPS update (and also took the opportunity to download other updates which took some time). Anyway, used the sat nav this morning and so far, it appears to be working normally now and the signal comes on in seconds!

Just says waiting for gps signal


Tom Tom needs comms with GPS satellites orbiting the earth.

Make sure you are outside your home so the GPS can find these signals. Initially it may take up to 5 minutes to make these connections. One the satnav knows where it is, all subsequent connections will be a lot quicker. :)

Some vehicles have windscreens with special coatings which prevent the satnav initialising with GPS satellites. If this is your problem, the only solution is to purchase an external antennae for your satnav. :(
