Original Blaupunkt Radio, 2 DIN's - "Porsche" slide switch...and... Options

[turk22]

All,

I have some pictures of my radio, which certainly appears original to the car, and I have a couple of questions.

First some front shots: (Note the black button on the side on the station select buttons, it pushes in and out, anyone know what it does??) I have not seen any other pictures of a radio with the "Porsche" AM/FM slide select (what have I got here?).




Here's some pics of the tags, what a bitch to get these pictures. In searching this site and google I've found some links to the FTZ-Nr. U108 number, but none look like this radio.




It has two DIN jacks in the back, both have 'tethered' plastic covers. (I'll try and get clearer pics, but the blood was rushing to my head..) One cover has two 'pins' in it, and the other has 4 'pins' in it, the pins appear to be aluminum, but not really sure:



anyone else have a radio like this and can tell me a bit about it?
thx,
Turk
