Hands free and wireless?

Is it possible to get a hands free phone that can be used in a car without the need for an engineer to have to come out to install and if so where is the best place to go?

PS. If it is are they generic or do they have to be for Nokia / Siemens only

A bluetooth phone (& headset) is what you need.

If you need a quick overview of what Bluetooth is and how it works then see here.

Has it ever been qualified if Bluetooth counts though as hands free???
