Thought I'd give a heads up to a little 'Streetwize FM Bluetooth Transmitter' unit I bought from Euro Car Parts for the princely sum of £9.99, for those who like me are running an older in car radio/CD player.
Plugs into the lighter socket, easy connection to a free FM Channel, Bluetoothed to phone.
Been caught out a couple of times as had the volume down on the radio but it outperforms the one I had in my van that was 4 times the price.
