Blaupunkt Frankfurt

I've bought a Blaupunkt Frankfurt AM/FM stereo for my car. I think the radio dates from the early to mid 1980s as it has a CD input and as such could have been fitted, though not when the car was new. It has a standard 7 pin DIN socket on one of the rear cables, presumably for the CD input, and I'm looking for either a schematic diagram or some advice as to which pins do what.
Does anyone on the BB know, or at least can anyone direct me as to where I may find out. I've Googled to no avail.
Unfortunately, the radio does not have a model number anywhere on it. I've attached a couple of photos.
I'd be grateful for any help and give my thanks in advance,
Chris

I've had a closer look at the front panel of this radio and what I initially thought was a 'CD' symbol actually turns out to be a pair of intersecting circles ?signifying a tape player. Maybe this radio is older that I think, possibly early 70s. This makes more sense as it is a 'shaft' type rather than the more standard DIN setup used regularly in the 80s (and also in the 70s too).
It does work and pulls in the signal very well on both AM & FM. It has outputs for 4 speakers and I also do have all of the knobs and other paraphenalia that go with it.

The input will take any auxiliary input I think, the only question will be can you control the input from the head unit. I have put an MP3 through my tape input, and can control the volume but not the player - so is ok.

To get the wiring diagram I contacted the manufacturer direct (Becker in my case) and got a reply back within a few days (including all the wiring diagrams)., I would try contacting Blaupunkt via their website and see if they can help.

Thanks. I contacted Blaupunkt both locally and internationally and gave them as much information as I could including a small update with the new information above. I've not heard back yet and was hoping that the BB may help. If not, I'll wait for a response from Blaupunkt.
Failing that I'll have to pull the radio apart and attack it with my multimeter - this is where a circuit diagram would be very handy.
At present the radio sits on the shelf in my shed plugged into an antenna, speakers and a spare 12V battery and tuned to my favorite sport and music stations.
