Seems like lots of people have issue with code for stereo not showing up on Honda/Acuras after battery being unplugged so I accidentally found fix. Before I use to get screen to put both codes but lately only one will show up but not stereo so I end up putting first code then open navigation screen and put second code anyway even that power button does not respond and show screen for code.I pressed Audio button then put code and it worked,it came back to life.
So procedure is Put first code into system,then press Audio then put second code anyway and it should come back to life.For some reason system stopped showing second code screen.
