Post# 28 downloads well & works fine except for this: when I arrive to a destination screen shows "Switch Off" option (in addition to back, nearby places, save trip... etc). If I click this big power on/off-like button the screen starts fading out & changing to white color, then whole unit jams with buzzing sounds and no way to get out unless you reboot the whole system. Did I miss any setting on sys.txt for my S100 WinCE6 unit?
