Non-audio guy here (although I am technical), so I ask for leniency if I'm in the wrong place.
I was just given a 2003 Pontiac Vibe w/stock audio. I wanted to take the JVC stereo from my truck and put it in the Vibe since the JVC has aux input. Well, I started taking everything apart in the car, but didn't disconnect the battery. Long story short, the adapter kit from the truck wouldn't fit and I put everything back together until I can get another kit. I didn't test anything after reassembly. Let me say that everything did work before I started doing any of this.
The next day the radio won't pick up any station. No biggie; I figured the antenna cable came loose. It was reluctant to unplug when I was messing around and thought I didn't get it back in enough.
Well I pulled it all apart today (battery dc'd this time) and the antenna cable felt fine. Pulled it out and reseated it. Put everything back together and still won't pick up a station. It does come on and plays CD's just fine. The "security" light flashes while the car is off. I read that this model doesn't actually have the security feature, so it's not locked out. The display doesn't display LOC either. I did try starting the security reset procedure just in case, but it didn't work.
I didn't do anything to the stock wiring, other than disconnecting everything from the back of the trim piece and radio. I read somewhere else that you can put the key in the ON position for 15 minutes and it may reset everything... but that didn't work. I tried disconnecting the battery (both terminals) for a couple of minutes, but this didn't work either.
Am I missing something? Is this fixable? Did I ruin the radio? It's no big deal, although I did want to put it in my work truck. But if this is something simple to fix I would like to be able to listen to something while in the car other than CD's, which I never carry.
Any help is greatly appreciated.
