My current truck has a CD player with the detachable faceplate and supposedly a little coded chip in the detachable part has to agree with a little coded chip in the fixed part, but thats not why I bought it. I figure the "hot stereo" market is big enough that there is gear out there to read and rewrite the chips or bypass it altogether. And even if I'm wrong about that...
...they'll still steal it even if it is useless to them.
I had the radio stolen out of my old, clapped out, base model 1978 Ford F-150 pick-up truck in 1993.
The radio was a stock analogue tuner AM/FM radio. No cassette deck. Not even stereo. It drove one tinny speaker in the dashboard. Mechanical push-button presets. A piece of aged crap. Wouldn't command five bucks at a garage sale.
Someone stole it. Smashed the window and cut it out of the dash with a Sawsall. Who did they think they would sell it to?
