Re: radio problem
Sounds like you do not have ACC. power to the HU, [radio].
Honda/Acura have 3 power leads in the radio harness, 12V constant, [hot at all times] sounds like you have that one as clock works, 12V switched, [hot in ON and RUN] sounds like you do not have it, and 12V switched (illumination), [hot when park/head lights are on] this lead may or may not be needed for your HU, either way it would not prevent HU from working. 94
