jj,

You've really got us working in the dark here, so we'll need you to help fill in the gaps.

"My audio remote controls 4 different components so everything is on one remote." Fill us in on this remote. 1. Is it made by kenwood? 2. is it a kenwood "universal". If it's not kenwood "branded", what is it? Where did it come from? packaged with your equipment new?

Holding down the "tape" key while learning. What tape key? on that "audio remote"? Is this "audio remote" a multi-device remote--Does pressing "tape" actually send a signal, or just put the remote into a "mode" to control the tape deck? Tape deck functions you'd want to "learn" are things like "play", record, pause, FF, RW, stop I don't think "tape"a function (ie, I don't think it means "tape this song" (if it did, it'd likely be a macro that 1. turns on the tape deck, 2. starts "record"). Are you thinking if you learn "tuner" you'll "learn" the full subset of commands for the tuner functions all in one batch learn?
