CD changer interfaces install at the rear of your existing factory fitted radio or to the pre-installed CD lead if one is fitted (depending upon radio and/or car type). If installation is to the rear of your radio, run the CD BUS lead from the interface to the mounting location of your changer.

Some Factory installed radios will accept aftermarket CD changers without the need for an interface and in such a scenario the CD changer will have the same software as that of a dealer supplied CD changer. For example radios that are compatible with the VDO 026 CD changer and Visteon 2080 CD changer don’t need interfaces.

Important: When installing interfaces ensure your keys are completely removed from your ignition.

Factory Fitted/Dealer CD Changers – An important issue

Factory-fitted/dealer CD changers are CD changers that are fitted at the factory or supplied by car dealers (i.e. Audi, BMW, Volvo, etc) and generally carry part numbers such as 786511203 as opposed to part numbers such as CHM-S630 that aftermarket CD changers have. Their overall styling is also a lot more basic than aftermarket CD changers.

These CD changers will only work with the radios that they were manufactured for and will not be compatible with CD changer interfaces that car audio shops supply. This is simply because the software used in the CD changers is very different to that used in aftermarket CD changers.

My car doesn’t have an ISO connector as standard, is this going to be a problem?

Your new car radio will not always connect directly to your car’s standard wiring harness connector. You will need to use a harness adaptor in-between your car’s wiring and your new radio's female ISO connector.

The harness adaptor will simply convert your car’s wiring into an ISO male that will then enable you to seamlessly connect this by push-fit into the ISO female found on your new car radio's harness. The wiring harnesses will provide the power and the speaker connections to connect to your new radio.

Why will my aerial lead not connect to my new radio?

You may require an aerial adaptor, as some cars such as Vauxhall models use a female socket instead of the conventional male plug. The adaptor simply pushes into your car’s female socket and the result is a male plug that fits your new radio. One is included with all new radios.

Some others models need an aerial adaptor because they use an amplified aerial. Basically, the radio feeds the aerial amplifier that is built into the base of the aerial via this adaptor. If you fail to use this adaptor, a poor radio reception could result.

My car has a Steering Wheel Remote Control, can I still use this?

If your car has a factory-fitted steering wheel mounted remote control and you want to use this to control your new radio you will need to fit a steering remote adaptor to keep that capability.

Steering remote adaptors are available to work with many car makes and models in conjunction with Alpine, JVC, Kenwood, Panasonic and Sony radios that have the ability to connect to a stalk control lead. You will have to check with each specific model for compatibility.
