In simple terms, CD & MP3 changer interfaces enable you to connect an aftermarket CD or MP3 changer such as an Alpine CHM-S630 or Sony CDX-T69 to a factory-fitted radio.

Please Note: Most CD changer interfaces and MP3 changer interfaces sold online are only compatible with aftermarket CD changers or aftermarket MP3 changers. They are not compatible with factory-fitted, car dealership supplied CD changers, as the software used is completely different to that used in aftermarket CD changers. This then means, that you can only connect your factory-fitted, dealer supplied CD changer to the factory radio it was designed to work with.

Interfaces?

CD Changer interfaces are small electronic control units or converter leads (dependent upon vehicle and radio) and their average sizes are, for the box type, 80mm x 35mm x 55mm and for the lead type approx 160mm to 400mm in length that enable your factory-fitted radio to communicate and operate an aftermarket CD changer, such as an Alpine, Kenwood or Sony, etc.

This option gives you a superior alternative to a dealer CD changer and enables you to keep the integrated look and functionality your factory radio offers, while at the same time avoiding high prices charged by dealer. Aftermarket CD changers are generally superior in quality to dealer CD changers offering faster load speeds, higher quality sound playback and more reliability.

Are they Universal?

CD Changer Interfaces are vehicle and CD changer brand specific. They are not universal. So, in other words, the interface for a Ford 5000 radio using an alpine CD changer will not work with a Ford 5000 radio using a Sony CD changer.

And an Audi interface made for a Concert radio using an Alpine CD changer will not work with a BMW Business radio using an Alpine CD changer. You must match the radio and changer brand with the correct interface.
