I run a cheap chinese radio in my saloon, cost me £13 off ebay under "Classic car radio", styled to look classic it fits the pattern of the ashtray remarkably well so doesnt look untoward. Does BT, AUX, USB, RADIO, comes with remote. Can feel its cheap and chinese but works remarkably well and audio quality is fab for what it is. Not original but doesnt look too far off. You will need a DIN adapter plate or make one yourself. Available on ebay for a stag for £32, bit expensive for a bit of plastic but makes it easier
