This allows to carry one less electronic device while still providing the needed navigation data and convenient ways for turn by turn voice guided navigation. The line now has expanded to include devices running Palm and Windows Mobile operating systems.

All devices run the "Que" software suite, including map display, routing routines, search in the map database, etc.
All devicies have WAAS/EGNOS capabilities.
Popular accessories include external GPS antennas, vehicle mounts/power adaptors and external speakers.
