renault clio 182
Hi, Ive recently installed a dension icelink plus in my clio 182. However, when I switch off the ignition it loses all of the settings. There is a free wire hanging (black with a yellow connector) Ive heard that this should be connected to the 12v live but it looks like an audio cable. Has anyone installed one of these in their car or have any idea what the problem might be? Thanks.
