Greetings! Welcome to Tezzaworld website, unfortunately you are a few years late to the show as nearly everyone has been and gone, there is still lots of useful archived material to read through, not many active users unfortunately, but that’s the way it goes, hopefully you are not too disappointed...
I have installed my sony headunit that i had lying around and there was already a panasonic 8 disc changer in the boot when i bought the car. The leads and everything were ran to the back of the radio. I got the power working but i'm not sure its compatible.(being panasonic with a sony headunit) only 1 lead won't fit the the circular one, is there some way i can get around this?????
doubt that sony/panasonic would be compatible without an adapter . cant make out anything from that picture, its too small. surely you new sony can play mp3's. cd-changers are nearly as old as cassette players at this stage!
In general, audio equipment manufacturers don't have standard interfaces, to try and encourage you to buy their own equipment. Even if you managed to get the audio pinouts, the control signalling would most likely be completely different.
hey man the panasonic cd changer will only work with a panasonic headunit, same as if you had a sony one. with branded units they have to be the same brand both ends, plus depending on the age of the unit too.
