I am such a total geek.
This is a factory AM radio for my '65 Mustang 'vert, modified to AM/FM stereo, 180 watts RMS through four channels, with a USB host mp3 decoder which will play from thumbdrives in the ashtray. All of the mp3 playback functions (prev track, next track, prev folder, next folder, toggle radio/mp3) are controlled by the radio preset buttons, which continue to function normally when in radio mode.

Auxiliary input and USB port in the rear:

Microswitches mounted on alignment rack ready to go in. Each microswitch is activated by one of the preset buttons and operates a function on the mp3 decoder board. Threaded rack allows for precise alignment over preset plunger.

Complete, ready to button up the case. From lower left to right: AAR AM/FM conversion board (sold through installer/dealers, so I farmed this part out), yellow impulse relay, 5v power supply (I wasn't happy with the sound quality of any of the 12v mp3 boards I found, so this is necessary), and just above that is the mp3 board itself feeding the bulkhead USB port through a pigtail. The impulse relay makes it a snug fit, but I really didn't want to locate it remotely. The relay toggles power to the mp3 board in response to momentary input from one of the microswitches. RF interference not an issue as none of the additional components are powered when the tuner is active.

Now if I could just get the car back on the road... :\
