Despite being based on the cross-platform XULRunner, TomTom Home lacks support for Linux. It is, for instance, impossible to update the maps in these devices by connecting them to another machine running Linux, even when using a common web browser like Firefox that normally allowed such an update under Microsoft Windows. However, the devices can still be read in a Linux OS as a disk drive. There is even software made by the community to manage some functions of the TomTom.
