I'm sorry about the issue. Do you have a windows or mac computer?
Can you please download / install the TomTom HOME software on your computer at the website below:
, then turn on your TomTom GPS, and connect it to the computer with the USB cable, then use the TomTom HOME program on the computer in order to update maps for it.
(Note: If the TomTom HOME program does not work, then try the MyDrive Connect program at the same website above.)
Please reply at the box below to continue troubleshooting. Thank you.
