I've tried searching for this but to no avail. I have a constant beeping coming from my radio area (maybe right side of the radio) that only stops when the car is running. It's a fairly quiet beep, not at all like the exceedingly loud car security alarm sound. But it is a battery drain, and very annoying, so I've got to fix it. Oh, and my code reader (Innova 3130) picks up nothing.

Anyone have this experience, and/or know of a solution?

 

Possibly the reminders to clean the tape head or the aerial? These can be turned off from the radio control buttons, but I forget the sequence....search will reveal it for you.
