Audio system does not come on. Battery ran down. Jumped off and charged battery

Must be worse. Had battery charged yesterday; today is dead again. Sounds like alternator is out. The diagram was not in the box where the fuses are in the interior. I understand the audio has to be rekeyed using a code provided, but I have to be able to turn the audio on. It does not. I just hope the Harmon Kardon audio system is not burned out. But now it sound like the alternator may be. Your opinion please.

At this point without seeing the vehicle, it's really hard to tell what's going on. Our technician is suggesting that you bring the vehicle in and have the charging system and battery tested. Once complete we'll have a better idea how to proceed with the radio issue. We're open Monday - Friday 7 to 6 and Saturday 7 to 4. Give us a call to schedule an appointment and we will be happy to help you.
