So i am working on adding an aux and bluetooth to my 1999 Volvo S70 T5m, with the stock radio and everything was going fine, all but one solder point was good, when the bluetooth controller(from a pair of wireless headphones) randomly stopped working and had a short. Not sure how since i left for 10 minutes to eat and didnt mess with it, but i came back and it just quit. And its going to be because of something stupid too, because its always my luck, but i cant seem to figure it out leaving me very frustrated.
