N810

I'm finding I need a full screen virtual keyboard for inputting destination info on Wayfinder.

'Enable stylus input methods' and Launch finger keyboard with finger tap' are both enabled in Control panel.

However, when I tap the screen on a text input box with finger or stylus, the small keyboard shows, which is nice but requires the stylus - which is trapped in the IT by the car mount.

I can't find out what I'm doing wrong so any advice appreciated.
