Certainly not as vintage as the Becker, however with a distinctly 1980s/1990s feel is the Blaupunkt Bremen which I have fitted in my 2007 Aero:
https://blaupunkt.com/cus/product/bremen-sqr-46-dab/ The cassette slot is not in fact a cassette slot and just a flap which reveals an SD card slot and USB etc. The unit is quite short front to back which makes it easy to install in the Aero. Comes with a plug in mini microphone for Bluetooth phone connection for calls and streaming. Expensive but very pleased with it.
