My battery died in my car yesterday, so logically I bought a new one and replaced it. Car runs great but now my stereo won't turn on. Tried checking the fuse box to see if it maybe blew a fuse but the guide on the fuse box doesn't indicate an accessory fuse. Just troubleshooting before I take it to the mechanic, if anyone has any experience shoot me a response. I have an alpine stereo deck, not the standard deck.

 

If the display reads c0dE, the anti-theft feature has activated and you must enter the security code to re-enable operation. The code was originally provided on a small card that came with the car. However many owners and some dealers put the code on a label and stick it somewhere close by. Look at the bottom of the ash tray or in the glove box, fuse box, etc. to see if it's there.

If you can't find the code, you will need to record the serial number off of the stereo and bring it to an Acura dealer so they can look up the code. You may have to remove the stereo to read the serial number.
