Fujitsu Siemens Pocket LOOX navigation system

Pocket LOOX navigation systems were powered by Navigon MobileNavigator|6s.  There were 9 maps supplied with device, covering 37 European countries. Main difference between N100 and N110 is that N100 did not have any built-in user accessible memory, but came with 1 GB Mini SD card. N110 on the other hand had 2 GB built-in memory and a free Mini SD expansion slot.

Alternative operating systems

It is possible to run Linux on Pocket LOOX 600. The latest supported version of Linux kernel is 2.4.19. Linux is loaded from a CF card, allowing a return to PocketPC 2002. But during restart, all contents of RAM are erased. To prevent data loss, users should backup RAM before restarting to Linux.

Work is being done to port Android to Pocket Loox 720. A port of Android 2.2 is running on the 720. It is possible to boot from either CF or SD cards; as mentioned above, a backup of all data is highly recommended.
