In-car audio gadget
Just because your car may not have Bluetooth or DAB, that doesn't mean you have to be stuck with Radio 2 all day. There are plenty of gadgets available that allow you to stream music, play audiobooks and take calls on the move.
Anker SoundSync Drive Bluetooth Receiver
The Anker SoundSync adds Bluetooth connectivity to any car with an aux audio input and a 12V accessory socket or USB port. It can also be used at home to pair a Bluetooth device up to speakers and stereos. It costs less than £20, so is much cheaper than buying a new audio system for a car.
