Go into Tomtom home and select update and it should update your software to the newest one and get your unit back working normal. If it says your unit is already up-to-date, then open your unit in my computer and copy the main folders from the unit onto the computer unless you have made a previous back-up in Tomtom home Then delete all of the folders that you copied from the unit off of the unit once you have made sure all of them are on your computer. Then update your unit from Tomtom home and it should work like normal. Make sure you have your maps backed up or you might lose them.
