My major personal problem with the WINCE-Version is still not fixed. The setting "Turn maps" which means North oriented maps yes/no is still not persistant. Whenever you switch from map viewing mode to navigation this setting is always reset to "turn maps = on" and if you want North up you have to set it again to no in navigation mode, most of the time that means that you are already on the road and driving and have to fiddle with settings.
@steiny180 I think you are talking about the Android version. This Windows/WinCE version never had alternative routes.
