Here are some tips. One might help:
- Try to disable your antivirus and firewall, use Firefox, and make sure that your computer is not going into stand-by or similar.
- Clear the cache before each update attempt. Also could do a soft reset before and after the update.
- Make sure you have the latest Adobe Flash Player and Java installed.
- Make sure you have all the latest updates and hotfixes/patches to your OS.
- In case the device looks like hung during the update or the counter stopped, just leave it. It will be fine in a few minutes.
- Check your network connections, make sure that the TT's network adapter is enabled
- Try to uninstall and re-install the MyTomTom application
- Try to use a USB port on the mainboard, rather than a USB hub (desktop PC)
- Any further issue: Try it on another PC, try it with different USB lead (below steps are Windows specific)
- Whilst the device connected, remove the drivers from the Device Manager (Windows/Control Panel), DELETE the drivers
- Remove the MyTomTom application and run CCLEANER (will remove your history, cookies, etc by default)
