Hi;my tomtom 820 device keeps switching on and off,what could be causing that

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.

this worked for my device where NOTHING else would, the original problem seems to come from updates. My device does not keep its settings What should do

If your navigation device shows only the start-up image or you see a flashing cross after you switch it on, it means that the TomTom application is not installed or cannot be found.

1. Connect your navigation device to your computer.
   
   
2. Reset your navigation device.
   
   TomTom HOME starts.
   
   
3. If HOME offers a new application, click Back.
   
   
4. Delete the TomTom application from your device and computer by clicking Manage my navigation device.
   
   
5. Reinstall the application by clicking Update my device.
   
   
6. Safely disconnect your device.

Your sd card doesn't match with your device. It can cause device memory demage later. Change or don't use recent sd.

Hi - have had the same problem - if you look on the tomtom website and support they have a list and one is flashing red cross. You need to follow the steps to format the tomtom. I did this and it worked and it included the update. i havent reconnected since i have it working now. I think its a software problem with HOME. Make sure you do a back up on home and make sure you follow step by step. close HOME before you start to reformat and also in the preferences turn off the automatically connect to home when you plug into your computer or it keeps flashing up on the screen to correct. the only solution is to format it. i bought mine two days ago and the first one stuffed up so took it back for a replacement. this one worked when i turned it on but turned out the flashing cross appeared when connected to computer (i have a mac). good luck
