I have a Fiat 500X which is 4 years old and I have been searching how to update the maps.
The instructions on the tomtom website say to download the software and purchase the maps, which is then transferred to usb and installed on the car.
The software does not show the fiat logo like the example, and says there is no device connected.

My simple question is, how do I update the maps on my car?
