My '68 Coupe has the Blaupunkt just like the photo. It still works great. These are far more common in the US cars than anywhere else.
The US tarriff laws used to tax cars on their values with all the goodies installed. However, there was no tarriff on parts. So all the manufacturers from Toyota to Mercedes would import the cars stripped down and the dealers or port processors would install the options. That's why the Frigi-king A/C systems were common in the US. The tax law was intended to generate jobs for American dealers and it worked for decades.
In the Hi-Fi shops of the day, you could buy Blaupunkt tuners for your home. So, American customers who had never heard of Becker, chose Blaupunkt because it carried that "Euro-chic" cachet.
I'm keeping my Blaupunkt as long as it keeps working. Funny but it seems to get Oldies stations better than Urban Contemporary.
