Scrapy Posted December 17, 2020 Share Posted December 17, 2020 So I just recently brought this 04 Audi noticed there was a issue with the radio been doing about it reading and seen some people have put a Ignition switch feed to turn them off my question is the only way the radio will work is if red and yellow are together the stations don’t save and noticed this green and black cable at the back any one shed some light thanks Quote Link to comment Share on other sites More sharing options...

CJS71 Posted May 9, 2021 Share Posted May 9, 2021 the yellow is the constant live and red is switched. swap them over the red to a live with ignition. Quote Link to comment Share on other sites More sharing options...
