BMW Business CD (CD43) Radio

This radio does not have Bluetooth but various Bluetooth adapters are available if you search online and some even display music information (Bluebus, Bluemusic, Grom, Dension etc.).

The Business CD (CD43) was Blaupunkt’s fourth attempt at a CD radio for BMW, following the Bavaria Electronic CD I/II and the Business CD RDS (CD23) – the latter eventually becoming one of the most unreliable and problematic BMW radios of the 1990s.

With the CD43, BMW switched to a fully digital platform, resulting in a unit that is significantly more reliable than its predecessor.

Key improvements compared to the CD23:
▪️ More robust CD drive design: better components, far fewer malfunctions, and — most importantly — a faulty CD drive no longer bricks the entire unit, meaning the radio remains usable.
▪️ Extremely reliable FM tuner: failures are very rare.
▪️ LED illumination: eliminates the common dark-display issue caused by burnt-out bulbs.
▪️ Improved display connection: elastomeric rubber replaces fragile foil cables, solving the pixel error problem.
▪️ CD-changer input and i-bus support: enables use with multi-function steering wheels and the E38 MID (e.g., as remote control for rear passengers). When paired with capable CD-changer emulator Bluetooth adapters, the radio can also display track titles and other metadata).
▪️ Improved sound processing
▪️ Longer display capable of showing more characters

The radio is used but in outstanding condition. The buttons show no wear, the side covers are original and fully intact, there are no pixel errors and the volume regulator encoder has already been replaced – a common failure point that most units sold online still suffer from.

The price is 499€ + shipping (only 1 left)

I guarantee that the radio will work correctly upon arrival. However, since these are original BMW units from the 1990s, I can’t give any warranty.
