I recently experienced a problem with my TomTom Go 520 – when docked, it connect to my Apple Mac computer fine, however when switching the TomTom on to use it, it displayed the start-up image with a white cross in a red circle – not a good sign…

…but after trawling the TomTom web site and Google, I managed to fix it…

The TomTom connected fine to my computer so the first thing I did was to back up all the files on my TomTom to the computer manually by dragging them across – I believe the white cross in red circle problem occurred when using the backup option in the TomTom Home application, so I didn’t want to use this in case it made the situation worse.

One thing to note is you MUST make sure you have a backup of the map files on your TomTom. I think these are linked to the actual device so if you delete them you may have problems downloading and reinstalling them.

I suspected that the white cross in a red circle error had occurred because of a corrupt file caused by a glitch when syncing or backing up using the TomTom Home application, so now I had a full backup of my TomTom files, I reformatted the TomTom and then copied all the backed up files back to the device.

This worked for me!!!

I suggest you only try this as a last resort if you cannot find any other solutions, and I accept no responsibility if you try this and are unable to restore your TomTom – all I can say is, this worked for me…
