Hi my tomtom 920 keeps shutting down .when programing it has been set not to shut down and allways does it just when you want it most. can you help. regards roger.

One possible cause is that your battery is low or the battery can no longer hold a (good) charge. In this case, the TomTom is shutting down because there's not enough battery to keep it running, even though it is plugged into a power source.

To determine if the battery is the cause, try to charge the TomTom battery .... using a (USB) connection to your computer, or a direct power source (i.e. while the TomTom is not being used). Let it charge for a few hours until the batter charge indicator shows that it is fully charged (or just leave it charging overnight).
Then, unplug the TomTom from the "charger" and power it up. If the TomTom (battery) doesn't hold a (good) charge, the device will shut down within a few minutes, e.g. 10 mins or much less.
When you (then) plug the device into a power source, and it doesn't stay on (i.e. it keeps shutting down after 10 seconds), you can safely conclude that the battery is the cause of your problem.

Hmm
Sounds like the updates had not quite finished.

Did you back up before ?
If so do a restore and try again.

If the battery is flat or dead it will never go on until you either charge the battery or change it. Batteries have a life of 2-3 years if used correctly.
That is charged using an AC source and definitely not starting the engine while the unit is plugged in.

1. Ensure that the battery is fully charged.

2. Try with different battery to determine whether the issue is with the battery or with the GPS device.

Hope this will help you.

Good Luck!!!!!!!

Turn on your tt. On the map screen tap the screen then tap the wrench (change preferances. Tap the forward arrow until you come to set time. Hope this helps.

Connect it to your pc then turn it on. It should either connect or ask you to connect to the pc. If tt home opens shut it down. Do a complete backup of your unit onto the desktop. DO NOT USE TOMTOM HOME TO DO THIS!!!! After doing a complete backup format the drive on your tt useing fat 32. Open tt home and let it reload your os. Do this a couple of times to get the newest os. Disconnect your tt from the computer the way you normally do and restart your tt. Reconnect your tt and do not let home start. Go to your backup and copy and paste your maps back onto the root of your tt. If you have any question email me.
Hope this helps

Try this website. It's the Tomtom forum...

It is probably your internal battery and needs replacement. There is a menu function to not shutdown when loss of power (under battery preference, after screen save). If you don't use the battery, try this.

If its still under warranty, get it repaired.. it sounds like hardware problem. Of course, you'll need to contact TT for repair options.

Do you have Bit torrent/ Ares or other torrent downloaders?
If so download torrent and open with bittorrent or Ares

Download the latest software tomtom home and do a gpsquickfix. THis will solve the problem and tell the unit where the satellites are for the next 7 days. May need to do gpsquickfix often.
