Richard,
I agree with Tom. It is most likely in place. I only mentioned it the
other day as for something to be aware of in case you had a problem
interfacing.
I would assume it is there, and only worry about it if there is a
problem getting the radio and tuner to see each other.
When properly set up: cable connected between radio and tuner, interface
menu set to Kenwood, tuner powered and turned on first, then when the
radio is turned on, you will hear a beep. No beep, no interface
between radio and tuner.
Take it a step at a time.
