I have not done more extensive testing to see if I can get into the service menu. If I remember right... There was a sequence of holding buttons and shutting off the car then different buttons then start the car. Not something you are likely to stumble onto....

I do have a person at the dealership (very teckie guy), and he is going to call Honda and maybe get ahold of some service personnel that work on those radios. I have my fingers crossed.. as it might be my last option...
