At first I thought my car stereo was haunted, which would seem odd, as nobody ever died using my car stereo.
Inexplicably, the volume would turn down to "0", and then refuse to turn up again. Well, it's not haunted... the "down volume" button has broken and now, going over a bump is enough to convince the stereo I have my finger pressed on the button.
"You just need a new face plate," Octavio told me as I bemoaned my dilemma. Ah HAAAA!!!!
But my stereo is a Jensen, and when I went to Jensen.com (the URL my stereo flashes at me each time I turn it off), it appears that Jensen Audio is no longer in business. I am screwed.
For want of an 1/8th of an inch of plastic, I will probably end up having to buy a new stereo.
