Right... Well I know that the law has changed and I know that my wife does a lot of driving (2-3 hours a day) and *cough* *cough* being female *cough* *cough* also does a lot of talking on the phone. Now she's not daft and doesn't do anything dangerous (in fact she tries to not use the phone) but I suspect that sooner or later she'll get nabbed for it so:
What's the legal requirement? Just that you don't use your hands for the phone? Can you press buttons as long as you aren't holding the phone?
And - assuming a simple holder and headset would be legal - would you recommend just that or that we splash out and get a proper car kit? (Which as I understand it is a external speaker and microphone so that apart from some way of dialing / answering the phone it's pretty easy)
