I have a 2003 Renault Head Unit and 6 Disc CD Changer but would like to add an auxiliary input for another source of sound, eg. iPod, DVD etc. I understand that an Auxiliary Input Adapter can be used to switch between the CD Changer and the aux device. Can anyone point me in the right direction for one that works with Renault equipment. Do Renault use their own socket designs or are they the same as Ford for example? I'm not an audiophile so please keep things simple! Many thanks.
