Does anybody recognize these CD boxes?

I found these 2 CD? boxes in a box of Porsche parts recently. Hoping the forum members can tell me what they are from. The numbers are 059 905 351 A and 059 905 351 B. I googled the numbers but got no info. They each have 6 pins. Mounting tabs are slightly different from one to the other. Thanks for the help.

8 pins were early 3.0 turbo, but bosch. edit: i see they are only 6 pin, so not 911/930.

Yes - those cd units appear to be from Audi - used on 100LS models between 1972 and 1977.

They had a high failure rate.

Dave is correct, the units were reliable to the extent that they were highly unreliable. You could almost count on the unit failing at some point.

Thanks for the input guys. Guess I have to give up my fantasy that they are off of a 917/935 etc. and are worth $.
