Very useful!

You can use this AUX cable to plug your cel phone into old 8-pin M-BUS Alpine car stereos even if they don't have a 3.5mm auxiliary port! It connects by the 8-pin port in the back of the stereo! If your Alpine car stereo model starts with CDM then this cable will definitely do the trick for you! Boom, instant music from the modern cel phone in the classic car! 😎

ATTENTION! This will only work on Alpine M-BUS stereos with model number starting with "CDM"

Read below for compatibility details! ("PXA03" refers to this model of Peripheral cable)

Plugs into the back of the stereo into the CD changer port (M-Bus port).

This cable provides iPod or 3.5mm/RCA Aux-audio input for most Alpine M-bus radios (ONLY models starting with "CDM")

Allows you to connect to the stereo by 3.5mm AUX/auxiliary or RCA (red/white) 

You must set the radio to "AUX" in menu options for the PXA03 to function

If a CD-changer (or other accessory/device) is occupying the M-BUS port you will be unable to connect the PXA03 because you are already using the necessary port for the CD-changer or other accessory!
