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.
