I took a new jazz for a test drive the other day.  It has a factory fitted  touchscreen navigation and audio system including a handsfree bluetooth cell phone connection.

I was surprised that I couldn't initiate a phone call from the touchscreen whilst driving - all the numbers and address book greyed out on the screen.  Had to stop and put the handbrake on to make the call.  Not sure whether I could receive a call whilst driving.

From a safety point of view I can see the reason - but is this normal for factory fitted devices.

Other than this, seems a great car, lots of features at a good price.
