Display has gone out on my radio, but radio still works. I checked to see if fuse is blown, but could it just be my radio is going?

I would be willing to bet that the car battery was recently changed. If so, the radio code needs to be reset. Call a Honda dealer and ask if this might be your problem. I think they will have to call Honda to get the code unless you have it.

Get a new radio. If it says "code" than you need code. Otherwise radio is done.
