The 'Club' is radio-only (on the left, behind), the 'Trabant' is radio-cassette(recorder), with the possibility for car use (model on the front). I'm not entirely sure, but I think Siemens was using Blaupunkt for their radio/cassette range of models. The Trabant has a slot-in cassettemechanism which is not very common.
There was a few boomboxes with auto-style slide in transports, that might make a nice thread,most are very rare at least around here. I have at least one, the big Lasonic but can't think of any more off the top of my head.
