I noticed yesterday as I was driving home that when I switch to the aux input... I get some really strange behavior

First off theres nothing pluged into the aux in.... but when aux in is select the play/pause icon blinks alternating between the two with a distortion like noise (very low volume) coming on and off in sync with the blinking icons....

Is this a know issue? is something wrong with my player?

I do have the preinit scripts, empeg gps (along with a gps plugged into the serial) and the TTS clock running...
