Austin - thats the safe way, I agree. one shouldn't look at all - just listen.

Its interesting that ergonomically, this 99p bit of plastic works very well... doesn't get in the way whatsoever on a thick modern steering wheel. And as its close, you could hear in an open top car.

But, as soon as one were to consider the need to have a power supply charger to stem the battery drain, it becomes dangerous and thus useless.

I was thinking more of hiding the phone out of view rather than have it on the steering wheel and then using an earphone for the voice only sat nav.
