Since the radio has been a out for a few decades now, has anyone figured out how to reset a Becker 780 without the impossible to find tool?

Ok, slightly different question... anyone know of someone with the reset tool to loan out?

You might have better luck checking with older car audio shops or Mercedes specialists; some still keep those tools around. Otherwise, occasionally they pop up used on forums or eBay, but they’re pretty rare.

Still looking. No joy.
