Re: Wiring 'Aux-in'(iPod)connectors to Car radios
I've noticed that commercially made adaptors tend to use a lead terminated with a stereo 3.5mm jack plug for the input lead, which is fair enough, since Ipods, MP3 players, etc. have a 3.5mm socket as the output. However I prefer to use a 3.5mm socket, preferably a headphone type with the extra contacts, so that the two matching resistors can easily be fitted, and, more importantly perhaps, the changeover from radio to aux & vice-versa is achieived simply by inserting or removing the external connection. A ready-made lead having two 3.5mm stereo jack plugs can be used to connect the Ipod, etc. to the radio.
