After searching the forum, I have found no solution to this issue. The aux-in in the center console does not work, even with volume turned all the way up on aux device, the stereo does not recognize it and will not switch to aux mode. Also, will not work with multiple devices, tried iPod, galaxy S5, even an old discman. Has anyone had a similar situation and come up with a solution?
I know mine will switch to AUX even if nothing is connected. This would be a guess, but maybe the AUX is not connected to the back of the head unit, so it won't switch over. Maybe that part of the head unit has gone bad. Just guesses, but i suspect the problem is closer to the head unit then the aux plug and cord itself.
