I didn't think people still use the old Tomtom devices but anyway two questions or suggestions:
1. Did you setup your TomTom account and checked if any updates available from TomTom site - official path. I doubt it is still supported by TomTom but pays to check.
2. Did you check iGo section - I didn't check the myself as I got rid of my TomTom years ago. So you can check and try at your own risk.
