Headunit not working, but illuminating

ViCiouS

First off, I've read all the stickies.

I'm not new to audio installs, I have all wires connected correctly. When I plugged in my aftermarket headunit there is no response from it at all. So I plugged the stock headunit back in, it will illuminate but not do anything else. It was working previously.

Is there a specific fix for this? Sport model 2010, no bose system.


On another note, the airbag light is flashing, when I try the fix it will get to the "diagnostic mode." but will not exit unless I turn the car off. At which time the airbag light will be back to flashing continuously.



EDIT: long day, i'm going to go check the fuses - checked, from what i can tell none are blown
