So everything in red is not working, even the CD player is not transmitting music changes sound tracks but not music, no radio also when I connect it at the cd player, not ability to increase or decrease volume, all in red is unusable, when the android device is ocmmect it simply takes over the audio and cna play only through that, without ability to use any of those red buttons including the vs player or radio.. If I want to decrease volume I need to do it in the android device. This is non sense, a simple search reveals that this radio does not have build in aux, so asking me connect the aux is not possible without the cd changer port filled in with the right hardness to change from cd to aux look at the right of the buttons
