This is my 2nd 8p Audi now, both had Concert head units, first car was spot on, good sound no issues, this one the radio works half the time, signal is poor, checked the strength via the hidden menu, when the signal is strong its strong and works ok, but the 2nd I go into town or built up area it starts to suffer, what could it be? I have tried using the AUX adapter but it sounds even worse.
