Hi guys. Please bare with me - new here. I've just retrofitted a premium amp on my 2012 LR4, upgrade from the high version. Done the CCF change in JLR SDD with - Audio from Highline to Premium, Small center speaker and With subwoofer. Amp is active, Logic 7 option is available, all good there. BUT. No Radio. I press the radio button on the touch screen, makes the sound, but doesn't want to change to radio mode.

I assume in the several attempts to set-up a previous amp (who proved faulty), some changes have been made that are interfering now with the radio system? I would really appreciate some help here. Thx
