I would be interested if it had a bunch of toggle switches and a few pushbuttons and some LEDs for programming; input and output.
I looked into replacing the old AM radio in my ancient dodge with a modern one, but eventually decided I simply liked the look & feel of that pushbutton thingie, and anything more modern just looked wrong in that car.
