Quick question. My tcu has failed as I had lost all sound and got the SOS message. I bought a jumper for the fiber optic and now sound came back. I have left it like this for over a year now but finally found a exact part number to replace it with. The question I have is will a tcu failure not show the phone setting in menu or allow the phone button on the radio to work. Now I did use the protool to turn off the tcu for the SOS error and now turned it back on but in the radio menu it doesn't show phone and button doesn't work and just won't to make sure with a tcu failure this is normal so when I get my replacement tcu I will be good. Thanks for the help
