Buzzing sound from cd tray
So I just tried to install an AUX cable in my OEM Panasonic W58814. Bought this one: https://www.ebay.com/itm/262224036269
Disconnected battery and installation seemed physically ok with the cable fitting ok in the empty cd changer port, but now the stereo isn't coming on at all. Display is blank, no response when pressing buttons. The small light on the little AUX box isn't lit up either.
The only thing happening is a buzzing sound from the stereo every second or so after turning the car on. It sound just like the (empty) cd tray is checking for a disc or something, so the stereo seems to be getting power at least. Naturally, I unplugged the AUX cable and put everything back together again, disconnecting the battery for a few seconds.
No joy. Still just the buzzing sound from the cd tray.
I'd greatly appreciate your thoughts on this one. Incredibly annoying.
Found someone else with the exact same problem. Unclear if/how they solved it.
Is this a good question?
