I know that there is a dedicated ICE section, but I think that I might get more replies to my questions if I post it in this section. So, I am considering replacing my Concert 3 AM/FM with a used Concert 3 with DAB, I understand that I will need a DAB aerial pre amp and probably a new aerial lead. Has anyone else done this swop on an early 2011 S4 saloon using used correct p/n parts and was component protection removal required for a used Concert 3 of the same age? Also does the new aerial pre amp cover FM and DAB and so can it just replace the AM/FM pre amp in the car, but get used with a new double Fakra cable? Thanks in anticipation!
