Thanks Scott and everyone else.
Radio gone. What an incredible nest of wires (still left)! I rolled them up, zip tied them and shoved them behind the left speaker, for now anwway. At some point I will follow them up the harness and unplug as many as I can.
If the radio had been half way decent, I would have kept it. The most valuable part, in my opinion, was the cigar lighter....All gone now.
I also took the radio volume control off of the handlebar. Now I have some place to mount a GPS.
As an aside, I had already taken the speaker set up off of the top box.
Lots more storage now.
