My 2nd Gen Prius aux is not working. It has an aux port, but no DISC/AUX button – just a DISC button. I bought the car secondhand and I'm wondering if the stereo system has been replaced and does not even have aux capability. Otherwise, I have tried everything, checking the connections, wiggling everything, even doing some soldering: Aux audio input fault on Gen II Prius - A Cheap Repair that works (Part 86190-53010) | PriusChat Any suggestions?
Likely stereo replaced look at the model of stereo in the front and look it up. you can go to the junkyard and pick one up that supports it for 40 buck is plug and play
