Genuine BMW (not Rover) BMW Business CD43. One screw door missing, but otherwise flawless. No dead pixels, comes with code card. These go for for $275plus on eBay plus shipping, duty, taxes, etc.
You can have this one for $250. Still terrible value compared to a new aftermarket deck that has way more features for way less money, but this one is a perfect fit and match for your dashboard, doesn't pose the same theft risk, and it will integrate with your factory BMW amplifier and its stupid built-in crossover network.
CD, AM/FM radio with 18 FM, 6 AM presents, RDS, balanced differential outputs, CD changer control, can be used with Dice or Peripheral kit to control an iPod or satellite radio.
