Hi guys,

I have a fundamental question regarding the control of CD changers. The question may be trivial, but I have never had a CD changer in my car. If I remember correctly, the connection (no matter which manufacturer / brand) takes place at chamber "C" of the radio. Now to my question: Are the protocols for the control also "uniform" or does each manufacturer use a proprietary protocol? For example, can a Blaupunkt changer be operated on a Grundig or Becker radio? Thank you in advance.

Thank you! Seems like manufacturers have learned their lesson in the meantime.
