We'll be posting the new Owners Manual shortly. Working on that next. In the meantime, see below how to switch orientation.
Menu -> Setup -> Screen Settings -> Toggle Orientation. Then just choose Portrait. It will need to reboot into Portrait Mode, so you will see it exit and re-initialize the map, you also have to confirm the acknowledgement page. The next time you turn you iFly on, it will boot the the last mode. Hope this helps.
