Check for obvious things like there are no blown fuses in the fuse box. One other suggestion is to check that you've not trapped any wiring under ...

The diodes should work, but be aware that they will drop ~0.7V or so, so you'll actually get ~11.3V instead of 12V. If the radio is okay with that, and if you can dissipate the heat caused by the diode drop * current drawn (may be small, but must be known), then you're okay. It won't backfeed either source. If you don't want the voltage drop, then you can ...
