My new-to-me 1996 K1100LT has what is probably a serviceable radio, but I don't know the anti-theft code. I believe the code is recoverable with BMW's help, but I'll need a radio chassis number. Therein lies the problem. I don't know how to remove the radio. The on-line manual shows a OEM tool that apparently shipped with the bike. It appears to be two wires whose ends are passed down between the radio and its carrier. However, the illustration is none too clear. Can someone who has this tool describe it in enough detail so I might make a suitable one myself? TIA
