friend just got a alpine CDA-9847 for his dd (92 camery) so we installed it today. Once we got everything back together we tested the am fm and cd and they all worked. He wanted to see how the flaceplate came off so i turned the radio off and removed it and then showed him the case for it. Then i slid it bakc on and when we turn it on we dont hear anything. no am no fm no cd. mute if off and volume is up. any ideas?

 

Does it have a theft deterrent feature that requires a code entry to make it work again?

 

I dunno but i can turn it on and go through menus and such. I can even see the little stero icon poping up in fm

 

pop it out and carefully pop it back in.... might fit but missaligned right now...... try that I have that exact head unit and no troubles at all on and off.
