I use a Sony mex BT3800 has sockets for a wired remote which I have mounted on the end of the transmission tunnel and also has an infra red remote too. It has a socket for an external Mic so the phone works very well through it as a hands free and it has a connection for an iphone / MP3 player via usb. Cost, I think, about €130
