A modification to fit a 3.5 mm stereo socket to the front face of a Becker Mexico Cassette to allow use of mp3 players and the like but still retaining AM/FM radio and cassette functions.

Interesting…
We’ve such a receiver in our classic car (see 1970 Becker Mexico AM-FM Cassette Car Radio showing operation & sound – YouTube « The Wiert Corner – irregular stream of stuff).
It would be a great way to add AUX to it, but I’d rather not modify the front-panel. Since the 450SEL69 has plenty of room, I will try to see if the above instructions can make the cable external so the AUX connector will be either near the arm rest or the glove compartment.
