SOLVED! This post got me on the right track. I always had VHF, BATT, #3 sig distribution etc. correct. What it turned out to be was I needed to map Pilot Radio trigger RADIO, not Pilot Radio trigger ICS. ICS is for intercom and RADIO is for radio. Once remapped it worked like a champ. Also, you do not have to hold it down once you get the radio menu options up.
Thanks ALL for your help...
