Hey, thanks everyone for the suggestions about the power supply. I'm really not sure why that didn't occur to me since I've been bitten by that in the past, and it's pretty common for me to ask customers the exact same question. I'm going to blame it on insufficent sleep and working on it way too late.
The problem did turn out to be an issue with an undersized power supply preventing the radio from powering on after both radios got enabled. They swapped the ones they had with a stronger one in the form factor they're dealing with (DIN mount), and the radios powered right up.
