Despite being based on the cross-platform XULRunner, TomTom Home lacks support for Linux.[65] 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.[66]
